Simulation

This is how your image may appear to a person with deuteranopia.

Deuteranopia is a more common form of colour blindness, occuring in between 1% and 5% of males (varying by race) and in approximately 0.1% of females. You may like to simulate how someone with protanopia or tritanopia views your image.

Simulate another

Use our Colour Blindness Simulator to reveal how your images may appear to users with a variety of colour blindness conditions. Upload a JPEG image of no more than 1000 pixels x 1000 pixels (100 KB filesize or less) to see how colour blind users may see it.
