About WordSolver
Free, precise, privacy-first tools for color puzzle players. Built by a daily player, for daily players.
Who We Are
WordSolver is an independent project created and maintained by Alex Rivera, a color puzzle enthusiast who has played Colordle and Colorfle every day since discovering them in early 2024. Alex has a background in front-end development and color science — a combination that turned out to be surprisingly relevant when it comes to building tools for color-based puzzle games. The project started as a weekend experiment to see if the Delta E CIE2000 color difference formula used by Colordle could be inverted efficiently to narrow down the list of possible answers from a player's guess percentages. It turned out it could, and the Colordle Solver became the first tool on the site. From there, the Colorfle Solver followed, then the daily answer pages, then the unlimited practice modes, and eventually the archive pages you see today. What began as a personal utility has grown into a comprehensive toolkit used by thousands of color puzzle players worldwide.
WordSolver is not a company. There is no team of developers, no office, no investors, and no revenue model. It is a side project built in spare time because building useful tools is something Alex genuinely enjoys. This independence matters because it means every decision about the site — from which features to build to how to handle data — is made by the person who uses the tools daily, not by a product manager optimizing for engagement metrics or a board of directors maximizing ad revenue. The site exists because it is useful, and it will continue to exist as long as it remains useful. There are no plans to monetize it, add advertising, or require accounts. Free means free.
Alex is not a professional color scientist, though the algorithms implemented on this site are drawn from professional color science literature. The Delta E CIE2000 formula used in the Colordle Solver is an International Commission on Illumination (CIE) standard for measuring perceptual color differences. The dual-space color mixing model used in the Colorfle Solver implements the same YCC and RGB weighted averaging that the Colorfle game uses. These are not approximations — they are exact implementations of published algorithms, and the results match the games' outputs within floating-point precision limits. Alex's contribution was not inventing these algorithms but implementing them correctly and building an interface that makes them accessible to people who just want to solve their daily puzzle without needing a degree in colorimetry.
Why We Built WordSolver
The motivation behind WordSolver was personal frustration. Alex was playing Colordle daily and repeatedly getting stuck at percentages above 90% without being able to identify the exact color name. The game tells you how close you are with a percentage, but it does not give you any mechanism for narrowing down which of the hundreds of possible colors is the right one. You either know the name or you do not, and there is no middle ground. This binary experience — either you nail it or you are completely stuck — felt like a missed opportunity. The percentage information is rich with signal; it tells you exactly how far away the target is from your guess. But converting that signal into a filtered list of candidates requires computing the Delta E distance between your guess and every color in the database, which is something humans cannot do mentally but computers can do instantly.
Colorfle presented a different but related frustration. The game shows you a target color and asks you to identify the three source colors from a palette of twenty. The number of three-color permutations is 6,840 — too many to brute-force mentally but trivial for a computer to enumerate and rank by similarity. The Colorfle Solver automates that enumeration, and the feedback-based elimination mode adds another layer of filtering by using the green, yellow, and gray signals from actual game guesses to rule out impossible combinations. This combination of exhaustive search and feedback filtering transforms the solving experience from vague intuition into systematic elimination.
The daily answer pages were added because not every player wants to use a solver. Some people just want to know the answer and move on with their day. There is no shame in that — the daily puzzle is supposed to be fun, and if looking up the answer is more enjoyable than spending twenty minutes guessing, that is a valid choice. The answer pages use a CSS-only reveal mechanism so you can read the surrounding content without accidentally seeing the solution. The unlimited modes were added because the once-a-day constraint limits practice. If you want to get better at Colordle, one puzzle per day is not enough repetition. Unlimited mode generates random targets from the same pool the daily game uses, giving you as much practice as you want without the 24-hour wait. Each tool addresses a different need, and together they cover the full spectrum of how players interact with these games.
Our Mission
WordSolver's mission is simple: provide the most accurate, most accessible, and most privacy-respecting tools for color puzzle players. Every decision about the site is evaluated against these three principles. Accuracy means using the exact same algorithms the games use, not approximations. Accessibility means the site is free, requires no account, works on all devices, and is designed for people who are not color science experts. Privacy means no data collection, no tracking, no accounts, and all computation happening locally in your browser. When these principles conflict with features that would be popular — like leaderboards that require accounts, or social sharing that requires tracking pixels — the principles win. There are other sites that offer those features. WordSolver is for people who prioritize precision, privacy, and simplicity.
We also believe that puzzle tools should complement the solving experience, not replace it. The Colordle Solver does not solve the puzzle for you — you still need to make guesses in the game and enter the results. The solver handles the combinatorial elimination that human minds are not well-suited for, freeing you to focus on the creative and intuitive aspects of color guessing. Similarly, the Colorfle Solver ranks combinations by similarity to the target, but you still need to evaluate the suggestions and decide which ones to try. The tools amplify human intuition with computational precision. They do not replace human judgment. This philosophy guides every feature we build and every decision we make about how the tools should work.
What Tools We Offer
WordSolver currently provides five categories of tools across two games. For Colordle, we offer a daily answer page, an interactive solver, an unlimited practice mode, and a full archive of past answers. For Colorfle, we offer the same four tool categories: daily answer, solver, unlimited mode, and archive. That is eight distinct tools, each designed to address a specific player need. Here is a brief overview of each.
Colordle Answer Today shows the solution to each day's Colordle puzzle. The answer is hidden behind a CSS-only reveal so you can read the strategy content without seeing the solution accidentally. The page includes the color name, hex code, a color swatch, and strategy tips for approaching similar puzzles. It updates automatically when the daily puzzle resets.
Colordle Solver is an interactive tool that filters the color database based on your guesses and the percentages Colordle returns. Enter a color name and its percentage score, and the solver eliminates all colors that would not produce that percentage. Each additional guess exponentially narrows the candidate list. The solver uses the Delta E CIE2000 formula — the same one Colordle uses — so the results are mathematically exact.
Colordle Unlimited generates random target colors from the same pool the daily game uses, allowing you to practice as much as you want. There is no guess limit and no daily reset. Each page load creates a fresh puzzle. This mode is ideal for building color vocabulary and testing strategies in a low-pressure environment.
Colordle Archive lets you browse every past Colordle answer on an interactive calendar. Click any past date to see the answer, complete with color name, hex code, and swatch. The archive is useful for catching up on missed puzzles, studying color patterns, and building your mental color library.
Colorfle Answer Today shows the three source colors, their weights, and the resulting target color for each day's Colorfle puzzle. Like the Colordle answer page, it uses a CSS-only reveal to prevent accidental spoilers. The page includes the component color names, hex codes, weight percentages, and the mixed target hex.
Colorfle Solver takes a target hex code and finds the closest three-color combinations from the twenty-color palette. It also supports a feedback refinement mode where you enter your actual guesses and the green, yellow, and gray signals from the game to eliminate impossible combinations. The solver uses the same dual-space mixing model as the game.
Colorfle Unlimited generates random Colorfle puzzles on demand, using the same palette, weights, and mixing formula as the daily game. Practice color mixing without the once-a-day constraint.
Colorfle Archive provides a complete history of all past Colorfle answers on an interactive calendar. Each entry shows the three component colors with weights and the resulting target, giving you a rich dataset for studying how different combinations produce different results.
Our Commitment to Accuracy
Accuracy is the foundation of WordSolver's value proposition. If a solver gives wrong results, it is worse than useless — it actively misleads players and wastes their time. If a daily answer is wrong, it undermines trust in the entire site. That is why we use the exact same algorithms the games use, not approximations or best-effort replications. The Colordle Solver uses the Delta E CIE2000 formula implemented in LAB color space, which is the CIE standard for measuring perceptual color differences and the same formula Colordle uses internally. The Colorfle Solver uses weighted channel mixing across both YCC and RGB color spaces, exactly matching the official game's output. When the solver says a color would score 85.32%, that is the same number you would see in the game at full precision.
We do not approximate, we do not guess, and we do not use machine learning. The results are mathematically exact within floating-point precision limits. Every calculation is deterministic: given the same inputs, the solver always produces the same outputs. This determinism means the results are reproducible and verifiable. If you ever see a discrepancy between the solver's output and the game's output, it is likely due to display rounding (the game shows two decimal places, the solver uses full precision) or browser color profile differences affecting how colors appear on screen. The underlying calculations are identical.
When accuracy issues are reported — and they occasionally are, usually because a game has updated its algorithm or color list — we treat them as the highest priority. A wrong answer or a malfunctioning solver undermines the core value of the site, so we investigate and fix these issues as quickly as possible, usually within the same day they are reported. We also proactively monitor for algorithm changes by comparing our answers against the games on a daily basis. If a game changes its target generation logic, we detect the discrepancy and update our implementation promptly. This ongoing vigilance is part of the commitment to accuracy that defines WordSolver.
Our Independent Status
WordSolver is an independent project. We are not affiliated with, endorsed by, or connected to Colordle, Colorfle, or any other game. We are players who build tools for other players. Our use of game names is for descriptive purposes only — to clearly identify which games our tools are designed to help with. We have deep respect for the games and their creators, and we design our tools to complement the puzzle-solving experience rather than replace it. We do not host copies of the games, we do not intercept game traffic, and we do not scrape game data. Our answers are generated independently using the same mathematical algorithms, applied to publicly available information about how the games work.
This independence has practical implications. It means we can design tools based on what players actually need, not what a corporate parent wants to promote. It means we can keep the site free and ad-free without needing to justify the cost to anyone. It means we can prioritize accuracy and privacy over growth metrics. It also means we have no official access to the games' internal code or data — our implementations are based on analysis of the games' observable behavior, published algorithms, and community documentation. This reverse-engineering approach produces accurate results in practice, but it means we occasionally need to update our code when games change their algorithms without notice.
We believe that independent tool-building is a healthy part of any puzzle game ecosystem. Just as crossword enthusiasts create clue databases and Sudoku players develop solving techniques, color puzzle players benefit from computational tools that handle the parts of the puzzle that are tedious or impossible to do mentally. WordSolver exists in that tradition — a player-made resource that enhances the experience for everyone who uses it, without competing with or diminishing the games themselves.
What Drives Us Forward
WordSolver continues to evolve based on user feedback and personal interest. Recent additions — the archive pages, the feedback-based elimination mode in the Colorfle Solver, and the searchable answer history — were all inspired by user suggestions. We read every email sent to hello@wordsolver.tech and consider every feature request, even if we cannot implement all of them. The features that make it onto the site are the ones that align with our three core principles: precision, privacy, and simplicity. Features that would require user accounts, collect personal data, or add complexity without clear benefit are unlikely to be implemented. Features that make the existing tools more accurate, more accessible, or more useful are always welcome.
Looking ahead, we are exploring several potential improvements. Better mobile responsiveness for the solver interfaces is a frequent request, and we are working on it. Expanded archive functionality, including the ability to filter past answers by color family or similarity range, would make the archive more useful as a study tool. A combined daily dashboard that shows both Colordle and Colorfle answers in one place would save time for players who play both games. These are all under consideration, and we will implement the ones that best serve the community while staying true to our principles.
If you have a suggestion, a correction, or just want to say hello, we would love to hear from you. Reach out through our contact page or email hello@wordsolver.tech directly. WordSolver is built for the community of color puzzle players, and your feedback shapes what it becomes. Every message is read by a real person — usually Alex — and every constructive suggestion is taken seriously. The best tools are built by listening to the people who use them, and that is the approach we are committed to.
