What is the color guessing game?
The color guessing game shows you a hex color code, such as #F2622A, and asks you to pick the swatch that matches it. There are six swatches to choose from and eight codes in a round. The wrong swatches start out very different from the right one and get closer with each code, so the last few take a careful eye.

How to read a hex color code
A hex color code is a # followed by six characters, read as three pairs: red, green, blue. Each pair is a number written in base 16, where the digits run 0 to 9 and then A to F. The lowest value is 00 (none of that color) and the highest is FF, which is 255 (as much as possible).
| Code | Red | Green | Blue | Color |
|---|---|---|---|---|
| #000000 | 0 | 0 | 0 | Black |
| #FFFFFF | 255 | 255 | 255 | White |
| #FF0000 | 255 | 0 | 0 | Red |
| #00FF00 | 0 | 255 | 0 | Green |
| #0000FF | 0 | 0 | 255 | Blue |
| #808080 | 128 | 128 | 128 | Mid gray |
Three pairs with 256 values each give 256 × 256 × 256 = 16,777,216 possible colors.
Tips for guessing colors from hex codes
- Find the biggest pair first. It tells you the dominant color. In #D0A714 red (D0) is highest, green (A7) is close behind and blue (14) is almost absent. Lots of red and green with no blue is a yellow or gold.
- Only the first character of each pair matters much. D0 and DF look nearly the same; D0 and 50 do not.
- Judge lightness by the total. Three high pairs make a pale color, three low pairs make a dark one.
- Equal pairs mean gray. The closer the three pairs are to each other, the less colorful the swatch.
- Know the mixes. Red plus green makes yellow, green plus blue makes cyan, red plus blue makes magenta.
- On the late colors, compare neighbors. When all six swatches are similar, ask which is slightly redder, greener or bluer than the rest, and check that against the code.
Daily and Practice modes

Who is this color guessing game for?
Anyone who works with color on screens: web designers, front-end developers, illustrators, and students learning how RGB works. It is also just a quick test of your eye. Colors look different from one screen to another, and night modes or blue-light filters shift them, so play with those turned off for a fair round.
