Farnsworth Munsell 100 Hue Test has been used for over 50 years as the definitive standard for testing color discrimination-
your ability to discriminate between various shades of a given color. The test
will tell if you're low, average or poor at discriminating color.
Here's how it works...
First,
you'll need a controlled daylight light source such as a SpectraLight® or Judge® color viewing booth.
Then,
you arrange four trays of colored caps in hue order. There's
a predetermined sequence for each tray. The closer
you are to the correct sequence, the better your color discrimination.
What do the results reveal?
The
results will tell you two things:
For
normal color vision, it reveals how well you discriminate different colors.
It
indicates if you have a color vision defect and identifies where your color confusion lies. For example if you're a "protan," then you would have weak red color discrimination. But if you're weakness lies in the green color discrimination area, then you would be a
"deutan."
