No preview. Just memory and feel.
Ready when you are
Blind Sliders strips out the live preview that the standard variants give you. You see the target color for four seconds, then a neutral grey screen with three sliders. You dial what you remember — but you can’t see the result of your dialing until you submit.
The HSV sliders behave the same as in any other variant. Hue moves around the color wheel from red through green to blue and back to red. Saturation moves between grey and a fully chromatic version of the hue. Value moves between black and the brightest version. In other modes, a swatch above the sliders updates in real time so you can compare your work to the target. Here, that swatch stays a flat grey. You’re operating from memory and from your understanding of how the sliders interact, with no visual feedback to correct you along the way.
The fastest way to improve at Blind Sliders is to commit slider positions to muscle memory before submitting. Drag value first — most people are reasonably good at remembering brightness. Lock in saturation next, since saturation strongly affects how vivid a color reads. Hue last, because hue at low saturation looks roughly the same regardless of where the slider sits, so sloppy hue placement on muted colors gets hidden anyway. Players who second-guess themselves after the four-second flash usually lose more accuracy than they gain.
Color accuracy is measured by CIEDE2000 perceptual distance — a perfect match scores 10 points, with a smooth fall-off as the gap widens. There’s no time pressure on submission, so the scoring is honest: how close did your remembered guess actually land. Five rounds, 50 points possible. A 35-plus run is genuinely rare.
