Hue ShufflePlay nowMix hue, saturation and lightness until it matches.
Color Matching keeps the target and your mix visible together. Drag hue, saturation and lightness until they agree, then Check match. You may check more than once on the same target. New target deals another destination with the same three sliders. This is adjustment with feedback in sight, not memory and not a race.
There is no shrinking timer and no growing grid. Difficulty is the target itself: some sit in a steep part of the hue wheel, some are pale and hide saturation. The controls stay the same. A later target is not a new rule; it is a new place to land. Replay or New target only changes the destination.
Each check reports a match percentage for the current mix. Best match is the highest check you recorded this sitting. Because the sample stays visible, a high number means you steered HSL onto a target you could still see. That is a different skill from Speed Color Match, where the sample is gone. Do not average the two.
People match lightness first and then hunt hue on a washed-out mix, which makes hue hard to see. Get hue roughly right, then lightness, then saturation. Another miss is chasing 100% on a display that cannot separate the last few steps. If the two swatches already look identical, check and move on rather than grinding the last percent. Keep the two swatches in one look. Peripheral vision lies about saturation. When you think you are done, look away at the page background for a second and look back; if the mix still holds, check. Checking twice on the same target is allowed and often the more honest number.
Use the live pair. Overshoot a slider and walk it back; the game rewards a stable land, not a dramatic first drag. A large hue move will make a previous lightness choice look wrong; that is expected. Fix hue, then re-check lightness, then saturation. If the patches look the same and the percentage is still mid, the panel has run out of steps — take the number and go.
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.
Target and mix stay visible, so this is adjustment, not recall.
New targets keep the same three sliders. Only the destination changes.
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.
