What could i do to find out if im color blind?

Testing: The most common type of "color blindness" is red-green color deficiency. Blue-yellow deficiency or true color blindness (achromatopsia) are rare. Color testing can identify which. The problem is a lack of certain types of cones or their opsins (light-sensitive compounds). Red-green deficiency can be adapted to fairly easily and is not very limiting, but the others can significantly impact vision.

Compare: Compare your color recognition with someone known to be color normal. For instance sort out a box a crayons and see if your matching is the same as theirs. You can of course go the the ophthalmologist and have yours tested with a color test booklet. And you can Google: "color vision test plates" and try out your color recognition on line.
