Guess the Logo Color

How to guess the logo color in five rounds

Every round names a brand and gives one short hint, then hands you three sliders. You guess the logo color by moving hue until the color family looks right, then saturation for how vivid it should be, then lightness for how dark or pale. Submit when the preview matches what you remember, and the two swatches appear side by side with a score out of 100.

There is no penalty for taking a moment. The sliders update the preview live, so the usual approach is to overshoot on hue first, find the boundary where the color stops feeling like the brand, then walk back toward the middle. Most players land their best rounds this way rather than by nudging a single slider a few degrees at a time.

Five rounds make one game. The total is out of 500, and the result screen shows a row of colored squares you can share without giving away which brands came up.

Why guessing a color is harder than naming a brand

Logo quizzes usually crop an icon and ask which company it belongs to. Recognition is easy because your memory only has to match a shape it has seen thousands of times. Color memory works differently. People remember that Coca-Cola is red and Spotify is green, but almost nobody remembers how red or how green.

The gap shows up in the scores. Players routinely name all five brands instantly and still average in the 30s and 40s on the color match. Hue tends to be close, while saturation and lightness drift, which is why the same brand can feel right at three noticeably different settings.

That is the whole puzzle here. You are not being tested on whether you know the brand. You are being tested on how precisely you stored its color.

How close is close enough

Scores come from perceptual color distance rather than raw RGB arithmetic. Your guess and the target are both converted into CIE Lab, a color space built so that equal numeric distances look like equal differences to the human eye, and then compared with a Delta E style measure.

This matters because RGB lies about distance. Two greens twenty points apart in RGB can look identical, while two blues the same distance apart look clearly different. Lab flattens that out, so a score of 90 means roughly the same visual closeness whether the brand color is yellow, navy, or magenta.

In practice a Delta E under 9 reads as a near-perfect match and scores in the high nineties. Around 15 you are still comfortably in the range where a casual observer would call it the same color, and that lands near 92. Past about 45 the two swatches start looking like different colors rather than different shades of one.

Brand colors that catch people out

Some colors are harder than they look. Facebook blue is much darker than most people set it, because screens and app icons tend to render it brighter than the brand value. Starbucks green is the opposite case, sitting deeper and less saturated than memory suggests.

Red is the most crowded family and the most misjudged. Coca-Cola, Netflix, YouTube, and Target all sit close enough that players who guess one accurately often carry that setting into the next red round and miss by a wide margin. Each has a different lightness, and that is usually where the points go.

Yellow and orange brands cause a different problem. Hue is easy to find, but the eye is unusually sensitive to lightness in that band, so a guess that looks correct at a glance can still score in the fifties.

Playing on a phone

The sliders were built for touch first. Each control is a full-width track with a large handle, so a thumb can reach the whole range without the fiddly precision a color picker usually demands. Nothing loads from a store and nothing asks you to sign in.

Scores and streaks are kept in local browser storage on the device you play on. That keeps the game instant to start, but it also means results do not follow you to another phone or browser.
