Color Memory
Can you recreate a color from memory alone?
A color appears for a moment and then disappears. Using three sliders (hue, saturation, and brightness), recreate the color you remember. The game calculates the actual color difference (Delta E) and gives you one score out of 100.

How to play
- Tap Start to begin right away.
- A color appears for 4 seconds. A shrinking bar shows how much time is left.
- When it disappears, use the hue, saturation, and brightness sliders to make the color you remember.
- Tap Check to see the original color and yours side by side, along with your score out of 100.
Tips
- When you look at the color, sort it out in your head in this order: what color family it is (hue), how vivid it is (saturation), then how light or dark it is (brightness).
- The sliders always start in the middle (hue 180, saturation 50, brightness 50). Get the hue right first and the rest gets easier.
- The backgrounds of the saturation and brightness sliders change to match your current color, so you can see which way to adjust.

Good to know
Color difference is calculated with the CIE Lab method, which is designed to match how the human eye perceives differences in color. Each game is short, so it's easy to play a few times in a row. Even if your score is low, comparing the original and your color side by side to see what was off is great practice in itself.
