Colordle Unlimited

One color is hidden and you cannot see it. Type a color name, pick it from the list and press Guess. Your guess is added to a list with its swatch, its name, its hex code and a percentage for how close it is to the hidden color, and the closest guess stays on top. Use what the numbers tell you to move toward the color: a guess at 90% is nearly there, one at 50% is far off. When a guess reaches 100% the hidden color is revealed and your guess count is your score. Press Next color for a new one.

Yes. Press Next puzzle for another hidden color at the same level, as often as you like, with no sign-up. A color you played a moment ago is skipped. Switch to Daily if you would rather have the one color everybody gets today at each level.

It is based on CIEDE2000, a standard formula from the International Commission on Illumination (CIE) that turns two colors into a single number, ΔE, for how different they look to the eye, so a difference you can hardly see counts for little and an obvious one for a lot. We convert both colors to the CIELAB space, work out ΔE, and show 100 × (1 − ΔE ÷ 100), never below 0, to one decimal place. A guess reads 100% only when its hex code is exactly the hidden color’s, and a different color never rounds up to 100%. We wrote the formula ourselves from the implementation notes that Sharma, Wu and Dalal published in 2005.

No. You can guess as long as you like, and the game ends only when you find the color. The number of guesses is your score, and the best result for each level is the fewest guesses you have needed (on a tie, the quicker time). Hints do not count as guesses, and neither does a name that is not in the list or one you already tried.

They change which colors can be hidden and which names you can type. Easy hides one of 235 common colors, such as red, lime or navy, and you can type any of 845 names. Medium hides one of 845 colors from the xkcd list, including two- and three-word names like dusty teal, and accepts 5,489 names. Hard hides one of 4,013 colors with one- or two-word names from the larger list, and accepts 5,504 names. The hints and the percentage work the same on every level.

From two open lists. The first is the xkcd color survey, where several hundred thousand people named colors on their screens; it is released under CC0 and gives us 845 names after we dropped misspellings and unsuitable names. The second is color-name-list by David Aerne, under the MIT license, which adds 4,942 more from its curated “best of” set. Names that look rude or like a brand were removed, and each name keeps its own hex code. The percentages and hints are our own.

According to the game’s own page, colordle.ryantanen.com, and to a Destructoid write-up, it was made by Ryan Tanenholz. It is a different game from this one, which was written separately for this site.

No. The Dles is an independent site. We wrote this version ourselves, with our own look, our own color lists and levels and a new hidden color every time you press Next, and it is not affiliated with or endorsed by the original game’s maker.

No. Here you guess by color name, and every guess shows its hex code next to the swatch, so you can learn to read hex codes as you play. Typing a hex code in the box does not count as a guess and does not use one up.

Nothing but the spelling. Colourdle, with the u, is how the word is written in British English, Canadian English and much of the Commonwealth, and Colordle is the American spelling; people searching for either mean the same game, and this page is for both. Color names in the lists use the spellings of their sources, so look for grey (and typing gray works too).

Easy has 235 colors that can be hidden, Medium has 845 and Hard has 4,013, so the same color rarely comes back. Every Next color picks a new one for that level and skips the ones you played most recently. What you can type is wider than what can be hidden: 845 names on Easy, 5,489 on Medium and 5,504 on Hard, with up to 8 suggestions shown as you type.
