Colordle Method
Colordle asks you to guess a hidden color as a six-digit hex code, with feedback on how close each red, green, and blue channel is. The efficient approach treats each channel as its own mini-puzzle and narrows them one pair at a time instead of guessing whole colors blind.
How hex and channel feedback work
A hex code is three pairs: RR for red, GG for green, BB for blue, each from 00 to FF. Colordle tells you whether each channel is too high, too low, or correct, so you get three independent directional clues per guess.
That means you should not think in color names. Think in three numbers, each of which you are pushing up or down toward a target.
A channel-by-channel strategy
Narrow each channel
- Start with a mid-gray like 808080 to get a direction on all three channels at once.
- For each channel, move halfway toward the indicated direction, a binary search per channel.
- Lock channels as they turn correct and keep adjusting the others.
- Remember FF is max and 00 is min; do not overshoot past the ends.
Converging on the color
The Colordle solver on this site tracks each channel's bounds and suggests the next hex to test, and the daily Colordle answer page reveals the exact code if you want to check your work.
Three binary searches at once
Because each channel gives independent high/low feedback, you are really running three simultaneous binary searches. Halving each channel range per guess lands most colors in a handful of tries.
Three channels, each 256 values wide
Colordle is not a colour-naming game, it is three numeric searches running in parallel. A six-digit hex code splits into three two-digit pairs, one per channel, and each pair runs from 00 to FF — which is 256 possible values per channel.
That is the whole structure. The feedback you receive is directional per channel: your red is too high, your green is too low, your blue is exactly right. Three independent reads per guess, and no reading is affected by the other two.
The table below sets out the three channels with their ranges, plus the size of the whole code space, which is what makes a blind guess hopeless and a channel-by-channel approach workable.
| Channel | Range and what the feedback says |
|---|---|
| RR — red | 00 to FF, told whether your red value is too high, too low or exact. |
| GG — green | 00 to FF, same independent high-or-low read. |
| BB — blue | 00 to FF, same independent high-or-low read. |
| Whole code | Three channels of 256 values each: 16,777,216 possible colours. |
256 values per channel comes from 00 to FF in hexadecimal; 256 × 256 × 256 is 16,777,216.
Watching a channel converge
The swatches below show a sequence of guesses against the same target, read left to right as progress. Each chip is a colour you could type; the label describes what the feedback on that guess would tell you.
Read the sequence as three separate tracks rather than as one colour getting warmer. The red channel settles first, then green, then blue — and the labels mark which channel is still open at each step.
This is why the strategy is to converge one channel at a time. A guess that moves all three channels at once produces three directional reads that are harder to act on than one read that closes a channel completely.
- #ff0000 Red far too high
- #800000 Red still too high, green and blue too low
- #7f3f00 Red settled, blue still too low
- #7f3fff All three channels aligned
Illustrative progression. The ring colour marks how much of the code is aligned: red ring for mostly unresolved, amber for partially resolved, green for a channel that has converged.
Converging each channel in turn
The order of operations follows directly from the feedback being independent. Move one channel at a time toward its target, and leave the other two wherever they are, until the first one comes back exact.
The steps below are that procedure. The discipline that makes it fast is the fourth step: once a channel is exact, never move it again, even if the overall colour looks wrong. Every subsequent guess should hold that value fixed.
Reading the target colour off a screenshot and converting it to numbers is optional but useful practice. The channels are the answer space; the colour on screen is just the rendering of three numbers.
-
Start from the middle of each channel
Guess 80 for red, green and blue rather than 00 or FF. A midpoint guess halves the remaining range in every channel at once, whichever direction each read points.
-
Read the three directions separately
Write down one direction per channel: red high or low, green high or low, blue high or low. Three independent reads per guess, six bits of information in one attempt.
-
Pick one channel and converge it
Choose one channel and keep halving its remaining range while leaving the other two alone. Closing a channel completely removes it from the search.
-
Never move a channel once it reads exact
An exact channel is finished. Hold that value in every later guess, so the remaining feedback is purely about the channels still open.
-
Halve the remaining range each time
Apply the same midpoint logic to each open channel. Two-digit hexadecimal values are a range, and a midpoint guess discards half of it regardless of which direction the feedback points.
-
Commit once all three channels are exact
When every channel reports exact, the code is the one you typed. Submit it rather than continuing to refine.
Colordle questions
How does Colordle tell you if you are close?
It gives per-channel feedback on the red, green, and blue values, telling you whether each is too high, too low, or correct. That is three directional clues per guess.
What is the best first guess in Colordle?
A mid-gray like 808080 is efficient because it returns a clear high or low direction on all three channels at once, letting you binary-search each toward the target.
How many colours can a hex code represent?
16,777,216. Each of the three channels runs from 00 to FF, which is 256 values, and 256 multiplied by itself three times is 16,777,216.
Do I need to know hex values to play Colordle?
No, but it helps. The game only needs three numbers, and every feedback line tells you whether one of those numbers is too high or too low. Reading hex fluently just saves you converting the target colour in your head.
