🎨 Hue Hunt
A colour-discrimination staircase. Brightness and saturation never change — only the hue gap shrinks as you get it right, until you find the limit of what your eyes can resolve.
🌈
Twelve rounds. Each correct answer shrinks the colour gap by 30%, so the task gets harder the better you do. The result is your just-noticeable difference — the smallest colour shift you can reliably spot.
