Hue ShufflePlay nowRebuild a hidden color using the sliders only.
Study the target, then hide it — your own preview hides too.
Blind Sliders lets you study a target, then hides every live preview. Rebuild the color with three sliders that stay visually neutral — the tracks do not paint themselves in your current mix. Only the numbers move. Reveal shows the target, your color, and a match percentage. Next color returns to a visible study stage and clears the old comparison. This is reconstruction without a running preview, not an illustration of pretty gradients.
Each new color hides the previews again. The sliders stay the same three axes. Difficulty is the target and your willingness to work from numbers. There is no shrinking clock unless you impose one yourself.
Each reveal is a match percentage for a mix you could not see while dragging. Best match is the highest of those reveals. It is a different skill from Color Matching, where both swatches stay visible. Do not blend the two numbers into one talent score.
Watching the slider tracks for a color leak is the trap. In the blind stage they stay gray on purpose. If you still see a changing rainbow on the rail, that is a bug, not a hint you are supposed to use. Another miss is revealing too early, before hue is even close, which wastes the comparison on a mix you already know is wrong. Set hue from memory first, while the afterimage is strongest, then lightness, then saturation. Reveal is a comparison, not a second mixing stage. The rails are supposed to be boring. Best match is the best recipe you recalled this sitting, unseen until reveal.
Read the three numbers as a recipe you are recalling, not as a visualization. If you cannot remember the target, reveal and take the low percentage rather than scraping the gray rails for a secret color. The rails are supposed to be boring. Next color is a new recipe. Write down nothing; the game is the sitting, not a log. Best match is the best recipe you recalled unseen until reveal.
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.
You cannot see your mix until you reveal it.
Each new color hides the previews again.
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.
