Ishihara Color Test
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.
4) Continue to the next Ishihara test, complete them all to help gauge your color blindness severity.
Notes:
1) Plate 1 and 24 are control tests – people with normal vision and all forms of color blindness should be able to distinguish these.
2) 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.
