Color Vision Test

Check your color perception for gemology studies with this Ishihara-style screening test

Did You Know?

  • Color blindness affects approximately 1 in 12 men (8%) and 1 in 200 women worldwide.
  • Most color blind people can see things just as clearly as others, they just can't distinguish certain colors.
  • The Ishihara test, which you're about to take, was developed in 1917 and remains the most widely used color vision test.
  • Color vision deficiency is usually inherited and present from birth, though it can sometimes be acquired later in life.

Test Instructions

Do's

  • Take the test in a well-lit room with natural lighting if possible
  • Sit at a comfortable distance from your screen (about arm's length)
  • Answer quickly based on your first impression
  • Make sure your screen brightness is at a comfortable level
  • Remove any tinted glasses or sunglasses before taking the test

Don'ts

  • Don't squint or strain your eyes
  • Don't take too long on each image - trust your instincts
  • Don't adjust your screen color settings during the test
  • Don't worry if you can't see a number - 'Nothing' is a valid answer
  • Don't be discouraged - this is for awareness, not diagnosis
