This Quiz Tests How Well You See Color
Now the folks at X-Rite, an organization specializing in the technology and science of color, and owner of the popular Pantone color system, are offering you the chance to actually test your "color IQ" online.
How it works: Presenting a series of subtly-varied linked color panels, several are out of spectrum order, leaving it up to the quiz-taker to reorganize so the gradient is correct.
After the test you'll receive a score on a comparative scale based on your age and gender, essentially letting you know how you stacked up.
Think you see the full range of the rainbow? Take the test to prove it: X-Rite Color IQ Test.
