Color is a weird thing. Think about it...when I say, "Imagine the color red" what do you picture? Red, right? But how do we know we're picturing the same color? We can't. We can only assume we are. That's because we can never really know what another person perceives, ocularly-speaking. Throw into the mix a case of colorblindness and we might has well be from different planets. The weird thing about colorblindness, of course, is those
that suffer from it assume they have it based on what other people are telling them. What if they're right and the rest of the population is wrong?? Interesting to imagine.
SO! How do you know if you're colorblind? You can take a test. Specifically, this test from Xrite. Keep in mind that a good score is a LOW score. I got a zero. Shocking, actually, considering the state of my vision. Apparently I can see color better than small writing on the back of an aspirin bottle.
