About the EnChroma Colour Blind Test

The EnChroma Colour Blind Test is a proprietary colour blind test designed to determine a person’s type and level of colour blindness. Created by EnChroma, an independent company based in California, the EnChroma colour blind test is the #1 online Colour Blind test for colour vision deficiency taken by more than one million people worldwide.

The EnChroma test is based on the Ishihara “hidden digit” test method developed by Professor Shinobu Ishihara at the University of Tokyo and is combined with a computer-adaptive algorithm to measure the type and level of colour vision deficiency (CVD). The three main types of colour blindness are Deutan, Protan, and Tritan. Learn more about the different types of colour blindness.
