Colour Match

Colour Match is one of the browser games on Bludle. Each day it shows a single target swatch, and beside it your own mix, which starts at black. Under the two swatches sit a red, a green and a blue control, each running from 0 to 255, with a box that shows the exact number.

The target stays on screen the whole time, so this is not a memory test. The hard part is reading a colour as three numbers: how much blue is in a deep navy, or how much green turns a red into an orange. You can move the controls as long as you like, but you get only one submission a day.

When you submit, the game shows the target's RGB values next to yours and the difference on each channel. Those three gaps are added together into your score, and lower is better. A statistics panel keeps your average difference, your best match and how many colours you have played, and a share button copies or sends your result. The result card also counts a streak across Bludle's games and points you to Afterimage, its memory-based sibling.

It is free with ads, runs in the browser with no download, and asks for no account. A round takes a few minutes, which suits anyone who works with colour codes or wants to train their eye for them.
