Hue Shift

Two colours. One is fixed. The other is yours to bend. Drag to shift hue and lightness until they match.

10 rounds. 10 seconds each. A countdown from 3 locks in your answer. Your total delta-E is your score -- lower is better. Like golf, but for your retinas.

Your Score

Sub-0.20 average across 10 timed rounds. That's not a score, that's a boast. Your spatial colour intuition is either trained or suspicious. This is an absurd result. I built the chroma scaling to make later rounds punishing. It apparently wasn't punishing enough. If you're doing this professionally - colour grading, display calibration - I'd believe it. If you're not, you should be. Genuinely good. You handled the hue-lightness trade-off well, kept your head when the countdown hit three. Consistent and controlled. You understood early that horizontal is hue and vertical is lightness, and you didn't fight the axes. Strong result. Mostly close, a couple of wobbles, nothing catastrophic. You clearly have opinions about colour. A solid run. Some rounds came together, others got loose - probably the high-chroma ones near the end. Not bad. The colour space is counterintuitive to navigate by feel - hue wraps, lightness is perceptually uneven - and you've come out reasonable. Decent. The scores that drag this up are probably the rounds where the countdown intervened before you could finish a correction. The timer picked off a few rounds. 10 seconds sounds generous until the countdown hits three and your hand makes a decision your brain didn't authorise. Room to improve, but the foundations are there. The rounds where you landed well show you understand the mechanic. Some solid rounds buried under a few that got away from you. The minimap helps if you use it. The drag controls take a round or two to click. Once that's in your fingers the scores drop fast. Worth another go. Mostly a first-game score. The interface is odd until it isn't, and 10 seconds per round is less forgiving than it looks. OKLCH is a strange space to navigate by drag and feel. The hue wraps, the lightness is perceptual not linear. It gets better.
