Hue ShufflePlay nowMark where a warm hue stops being red and starts being orange.
Is this closer to Red or Orange?
Red or Orange? uses the same seven-choice search, but the path is warm hues, not turquoise. Each swatch is a large field of a red-to-orange color. You pick the word that fits. The search only reports a split when your labels actually change along that warm path. All red or all orange means no boundary was observed. Jumping between the two words too often means the run is too unstable to quote a number.
Seven judgments, one narrowing range. Later swatches are not a new game; they are simply closer to wherever your previous answers left the remaining interval. Replay starts a fresh warm range, not a copy of a blue-green result with two words swapped.
The useful output is a hue along this red-orange sampling path, or an honest refusal to name one. It is not a universal border between the words red and orange in language, and it is not a medical finding. Different screens will move the same seven answers.
Reading a leftover degree from a previous site or a previous game and expecting it here is a miss. This path is warm hues only. Another miss is forcing a number after seven identical answers. If you never switched, there is no conversion to report. Sunset colors crush together under warm lamps. If the room is yellow, expect more orange words. That is the sitting, not a personality. Keep the same lamp if you replay. When a split does appear, treat it as where you changed the word tonight, on this glass.
Warm hues collapse together on cheap panels and in yellow room light. A run of all orange is a real outcome, not a failure to find the secret number. The search path is red through orange only; do not import a turquoise degree from Blue or Green. Keep the same lamp if you replay. When a split does appear, treat it as where you changed the word tonight, on this glass.
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 swatch stays large. Only the hue creeps.
Replay starts a new search from a wide warm range.
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.
