DaltoTest - Color Blind Test

Olivier Morel

About this app

DaltoTest checks your color perception wherever you are, with five
historical color vision test methods: no appointment, no specialized
equipment, no account to create.

FIVE METHODS
• Ishihara plates: numbers hidden in colored dots, a red-green test
• Farnsworth D-15: arrange 15 caps in a gradient, blue-yellow coverage
• Extended FM-100 test: 96 caps in 4 rows, more sensitive to subtle
differences
• Lantern test: identify brief signal lights, professional-qualification
style
• Test inspired by the Cambridge Colour Test: spot a ring hidden in a
dot mosaic

Wondering about your color perception? It happens: you wonder if you
really see red and green the way everyone else does, or if your kid
keeps mixing up colors at school. DaltoTest lets you check in a few
minutes, wherever you are, no appointment needed.
