Hue ShufflePlay nowRebuild a hidden target before ten seconds run out.
Study the target. When you start, it hides and the clock runs.
Speed Color Match shows a target, then hides it and starts a ten-second clock. You rebuild the color with hue, saturation and lightness and submit before the clock hits zero. If time runs out, the current mix is settled as your answer. This is matching from memory under a deadline, not a leisurely mix with the sample still visible. After the settle you see how close you got, then a new target.
The clock does not get shorter. What changes is the target itself: a new hue neighborhood each round, so you cannot reuse the last mix. Three sliders stay the same. The skill is deciding which axis to grab first in ten seconds — usually hue, then lightness, then saturation — and not chasing all three at once until the last moment. Start the match only when you have actually looked at the target. The ten seconds are for mixing, not for a first glance.
Each round records a match percentage for that mix against that hidden target. The session best is the highest of those percentages on this screen. It is not an average of your life in color, and it is not comparable to a friend on another phone. A lower number after a glare-filled minute is information about the sitting, not about your eyes.
The common panic is dragging all three sliders in tiny jabs until the clock expires with a muddy mix. Pick hue first while the afterimage is fresh, then lightness, then saturation. Another miss is watching the sliders instead of remembering the target, so you optimize a color you are inventing. If the clock dies while you are still hunting saturation, submit anyway; the settle is the round. Next target is a new memory, so do not leave the last mix sitting as a starting point you then fight. Keep the same room light if you chase a personal best.
If you glance and start in the same motion you will spend the clock reconstructing a color you barely saw. After a settle, glance at hue error first; if hue is already close, remaining seconds on a later round should go to lightness, then saturation. Replay is a new hidden target, so reset that order instead of copying the last slider positions. The game is independent tens, not one long mix interrupted by a clock.
Stay on this page until the round is finished rather than bouncing to another game mid-score. The controls you just used are the whole rule set; nothing is hiding in a settings panel. If a result surprises you, replay once on the same screen before you change rooms or devices. That second sitting is the only comparison this site can honestly support. Everything else — other phones, other people, other times of day — is a different experiment. Use Play again or Next round from the same seat. The copy on this page describes this game only; it is not a template with the title swapped.
The target hides when the timer starts. You mix from memory under pressure.
A new target appears each round. The clock does not get friendlier.
These three routes are only suggested sequences. You can open any of the sixteen games on its own, leave a route halfway, or skip the pairing entirely. Each game keeps its own score on this screen and this sitting. Nothing here adds those scores into a combined rank, a skill grade, or a color-vision result. Play the first game to notice one kind of judgment, then the second to see how that judgment changes when the task is slightly different.
Start at a color-name boundary, then hunt for a single off tile.
Blue or Green? asks you to name a turquoise as one familiar word or the other. Spot the Different then asks you to find a single off tile among many similar ones. Start with the naming game so you feel how a hue can sit on a boundary; then hunt for a tile that is only a little off. The first game is about the word you choose. The second is about a visual difference with no name attached.
Remember one color, then rebuild another with the previews hidden.
Color Memory shows a target, hides it, then offers six close options. Blind Sliders hides the mix as well, so you rebuild from hue, saturation and lightness numbers only. Do memory first: you still see the choices. Then try blind mixing, where even your own swatch is gone until you reveal it. One task is recognition among near-misses. The other is reconstruction with no preview. Completing both shows whether you hold a shade better when you can compare, or when you mix it unseen.
Put hues in order, then mix a match with three sliders.
Hue Sorting keeps two end tiles fixed and asks you to swap the middle until the gradient is smooth. Color Matching keeps the target visible and lets you drag three sliders until the mix agrees. Sort first so you feel the slope between two anchors; then mix a single target by hand. Ordering is about relative steps. Matching is about landing on one destination. After the pair you can see whether you are steadier at arranging hues or at steering HSL onto a sample that stays on screen.
A score on Hue Shuffle is a count of what happened in this browser, on this display, in this room. Brightness, color temperature, night mode, True Tone, and the kind of panel you are looking at all change how close two colors appear. The same round on a phone and a laptop is not the same stimulus.
Room light and viewing angle matter as much as the hardware. A window behind you, a warm lamp, or glare on glossy glass can hide a difference that was obvious a minute earlier. Sit still relative to the screen if you want two runs to be comparable at all.
Fatigue and attention move the result even when the device does not. A long session, a second monitor, or playing while distracted will scatter your answers. Repeating the same game on one device, with similar light, is the only comparison that has much meaning here.
Do not treat another person's score, or a score from a different phone, as a measurement of your vision. These games are for noticing how you judge color in the moment. They are not a medical exam, not a color-blindness test, and not a calibrated lab result. If you only have a minute, remember three things: same device, similar light, no medical story. Everything else on this page expands those three.
Compare how this game asks you to look, then open a neighbor if you want a different kind of judgment.
