A target gradient. A set of colour sliders. One number out of 100 that tells you how close you got. Descent is a quiet test of colour perception. You read a gradient, move RGB, HSB or CMYK sliders until yours matches, and see the two side by side with a score. Nothing else on the canvas but colour. CASUAL Untimed matching with no pressure. Pick RGB, HSB or CMYK and take as long as you like. DESCENT Timed levels that tighten as you go. Each level gives you less time and demands a higher score. Your best level is recorded. MESH Drag the points of a 3x3 mesh to rebuild a multi-point mesh gradient. Harder than it looks, and strangely calming. SCORING Every round ends with a score out of 100 and a direct comparison of the target against yours, so you learn where your eye drifts: too warm, too dark, too much cyan. DESIGN Version 4.3 is a ground-up redesign. Pure white and ink, with colour reserved entirely for the gradients themselves.
