Ishihara Test for Color Blindness
Ishihara Color Test Instructions
Plates 1 – 17 each contain a number, plates 18 – 24 contain
one or two wiggly lines. To pass each test you must identify
the correct number, or correctly trace the wiggly lines.
1. Sit approximately 75cm from your monitor, with each
circle set at eye level.
2. Preferably have mild natural light and no glare on your
screen. Interior lights and glare can alter the color of
the pictures.
3. Attempt to identify the hidden number or line within 5
seconds then click on the image (left mouse button).
4. Upon left clicking, the answer will be revealed along with an analysis explaining
your condition if you got it wrong.
5. Continue to the next Ishihara test, Complete them all to help gauge your color
blindness severity.
6. Share the test with your friends!
Notes:
l You can toggle back and forth between the original plate and the answer by
clicking on the plate itself.
l Plate 1 and 24 are control tests – people with normal vision and all forms of color
blindness should be able to distinguish these. These two plates are particularly
useful for identifying cheeky behaviour when testing children!
l This test cannot guarantee complete accuracy. Your monitor and quality loss of
online images may affect the original colors used. Should these tests suggest
that you may be color blind, you should seek professional confirmation.
l You need to have JavaScript enabled to reveal the answers. For any further

NEW: A man by the name of Antony Tran has converted my test into an Android App,

also tell you what color something is just by pointing your device’s camera at it – VERY
handy for us color blind people.
