Huewheel

What Huewheel trains

Huewheel works your reading of color relationships: seeing how two or three hues sit against each other on the wheel and recognising the shape they make. Complement, analogous, split-complement, triad and tetrad are not styles but angles, and once you can see the angle you stop guessing which colors will hold together. The game keeps saturation and lightness in a steady band so the only thing changing is hue, and it prints the target's position in degrees, so the geometry is visible rather than merely felt.

How to play

The day's target sits on a wheel with its hue angle labelled. Rounds one to five are multiple choice with four options, A to D: find the complement, then the analogous pair, then the split-complement pair, then the missing member of a triad and of a square tetrad. In the triad and tetrad rounds one member is given and marked on the wheel, so you complete a shape rather than invent one. The sixth round switches from recognition to production: turn a pointer to any valid angle of a named relationship and lock it in, by dragging the wheel, tapping the − and ＋ buttons, or using the arrow keys (Shift for ten-degree jumps, Home for 0°, End for 180°). Decoys tighten as you go, from roughly forty-five degrees off in the first round to twenty-five later. A checkbox marks each option's position on the wheel, keeping the relationships playable without relying on color discrimination.

How scoring works

In the multiple-choice rounds the correct option scores 100 and the nearest wrong option scores 50, so being close is worth something; anything further out scores nothing. Once you answer, every option's hue angle is revealed and the correct one marked, which is where most of the learning happens. In the dial round your error is the angular distance to the nearest valid angle of the relationship, and the round scores 100 minus twice that error. Within 12° counts as a hit, within 24° as close. Your daily result is the average across the six rounds, out of 100, alongside a count of clean hits. Score 60 or more and your streak continues.

What your score means

Read the daily number as a band, not a measurement:

Outcome	Rough interpretation
Score 60 or more, mostly clean hits	You read the angles, not just the colors, and 60 is the score that earns the day
Score 60 or more, mostly nearest-wrong picks	Right neighbourhood, wrong exact relationship; the half-credit is carrying you
Below 60	The schemes are still names, not geometry

Only one threshold is real here: 60. Everything else is shape: a day built from clean hits and a day built from nearest-wrong picks can land on the same number and mean different things, which is why the hit count beside the score is worth reading. A single day is noisy too: one badly judged decoy costs a lot over six rounds, so the trend is the honest signal.

Common mistakes

The most common error is confusing split-complement with analogous. Both are pairs that straddle a centre thirty degrees either side; the difference is whether that centre is the target itself or its opposite. Look first at which half of the wheel the pair sits in. A second trap is treating "opposite" as "very different-looking": the true complement is a specific angle, and a hue that merely looks unrelated is often the nearest wrong option. Third, people ignore the given member in the triad and tetrad rounds, though it is the strongest clue on the board, since it fixes the whole shape. Fourth, reading the swatch instead of the wheel: perceived hue is uneven, so equal angles do not feel like equal jumps, and the degree labels are more reliable than your impression.

Practice progression

(5 min, beginner) Play today's six rounds with the position checkbox on and name each relationship as an angle before you answer: complement 180°, analogous ±30°, triad 120°. (10 min, intermediate) Turn the checkbox off and answer from the swatches alone, then switch it back on to check. (weekly) Read color wheel relationships and color harmony schemes back to back, then build one real palette per week using a scheme you scored badly on.

The science behind it

The wheel is a convention, not a law of nature: it arranges hue as a circle because hue is genuinely circular in perception, but the spacing depends on which wheel you use, and the classic schemes are named angles on it. Whether those angles predict what people find attractive is a separate, empirical question. Schloss and Palmer, studying responses to color pairs, showed that judged harmony and judged preference are distinct: the pair you call harmonious is not automatically the pair you like. The wheel gives you structure; taste and context decide the rest. For the underlying axes, see hue, saturation and lightness.

Limitations

Huewheel is a game and an informal self-check, not a clinical or diagnostic tool. It runs on an uncalibrated screen, so colors differ between devices and results are not comparable across them. It scores your reading of one particular hue wheel, which is a modelling convention rather than a measurement of your eye. Scoring well does not make a palette good, and scoring badly does not mean you have a color vision difference. If you want to know about that, see color vision differences and, for a real concern, an optometrist.

Where it shows up

Relationship reading is what turns color choice from trial and error into a decision you can defend. A brand designer given one fixed corporate hue has to produce a secondary and an accent that do not fight it, which is a split-complement or a triad, chosen deliberately rather than a swatch picked because it looked nice next to the logo. An interior designer working from a client's existing sofa needs a wall color that sits in a known relationship to it, because the sofa is not moving. A stylist uses the same geometry at a glance: this scarf is the near-opposite of that coat, so it will read as a deliberate accent rather than a clash. A data journalist choosing categorical series colors needs them spread widely enough around the wheel to stay distinguishable in a legend, and a triad or tetrad does that automatically. A gardener planting a border for July is doing it too, months ahead and from memory. In every case one color is already fixed by something outside your control, and the question is what to put beside it. Knowing the angles gives you a shortlist in seconds instead of an afternoon of swatching.

Frequently asked questions

Which relationships does it cover?

Complement, analogous, split-complement, triad and tetrad, one per round, with a final dial round on one of them chosen for the day.

What counts as correct in the dial round?

Any valid angle of the named relationship: a triad has two, and a tetrad three. You are scored on the distance to the nearest one, with 12° counting as a hit.

Do I lose everything for a wrong answer?

No. In the multiple-choice rounds the nearest wrong option still scores half, and after you answer every option's angle is revealed.

Can I play it without relying on color?

Yes. Tick the box that shows option positions on the wheel and each option appears as a lettered marker at its hue angle, so the geometry is readable on its own.

Why is the analogous option a pair?

Because analogous means both neighbours, one on each side. The split-complement round is a pair for the same reason, but straddling the opposite point instead.
