Color Blindness Test

Color Blindness TestTry a color blindness test that compares color pairs and highlights possible color vision difficulty patterns.How Color Blindness Test worksThe Color Blindness Test is a practical screen for spotting color differences on your current display. It gives a readable breakdown of missed ranges while staying careful about the limits of browser-based color testing.How to play

Set your screen to normal brightness and disable night-shift or strong color filters if possible.

Look at the two color panels shown in each round.

Choose Same if both sides appear identical.

Choose Different if you can see a color difference between the sides.

Review the result breakdown to see which color ranges were missed or confused.

What it measuresThe Color Blindness Test screens how well you separate close color pairs across several families, including red-green, blue-yellow, pale colors, low contrast, and saturation-based differences. It measures performance on this display in this environment, not the full biology of your vision.How scoring worksYour score is based on correct same or different decisions across all rounds. The result also separates real missed differences from false alarms, then groups misses by color range so you can see whether errors cluster in one family.What affects your result

Screen brightness, color calibration, blue-light filters, and ambient lighting can change color separation.

Low-saturation and low-contrast colors are harder for everyone, especially on dim displays.

Fatigue and rushing can create false alarms even when the colors are technically visible.

How to improve

Use neutral viewing conditions Turn off night mode, avoid colored room lighting, and use a normal brightness level.

Do not rush subtle pairs Some rounds are intentionally close. A short pause can separate true color difficulty from a fast guess.

Repeat before concluding If the result surprises you, repeat on another screen or in different lighting before assuming a pattern.

Common mistakeThe common mistake is treating one missed pair as a diagnosis. A browser test can show which color ranges were difficult in this run, but it cannot name a condition with clinical certainty.Worth knowingMost inherited color vision deficiencies involve red-green separation, but screens add another layer: brightness, contrast, night-shift filters, color profiles, and ambient lighting can all change how close two colors appear.
