Color Blindness
Test

A color discrimination test based on the principles of the Ishihara Color Vision Test (1917). You will be shown 4 colored squares — one is slightly different. Tap the odd one out.

Before you start — important
Screen settings affect results. For accurate results:
· Disable Night Mode / Night Light
· Turn off True Tone or blue light filters
· Set screen brightness to full
· Do not wear tinted glasses

This is a screening tool only and cannot replace a clinical diagnosis. If you suspect color vision deficiency, consult an eye doctor.
