Ah, but this test looks for hue, not intensity or saturation. The results chart has greater variety in intensity than the actual test chips, in my opinion. One of the keys to this kind of test is to squint and if you're uncertain, switch two tiles and see which is warmer (or cooler) in hue.
I switched frequently, but I was thinking that hue, intensity and saturation were all involved. That may be why I didn't score better, but I didn't score poorly, either.
I have frequently been given color tests when I complain about certain things with my vision. The doctors always assume I am color blind, but I pass their tests every time. I think I have a different issue, but I am not sure what it is. For example, when trying to read the green and white signs for street names, it takes me a second or two longer to correctly read them. But when I am in Virginia, where blue and white signs are popular, they are easier for me to read. I think my brain reacts faster because there is more contrast with blue and white (or so my brain thinks). It may also be that green and white signs easily blend in with nearby trees whereas blue and white does not.
I am a very visual person. I learn best by visual methods and I have very good visual memory. In fact, if I have to learn anything that is not visual, I create a visual process in my head to help me understand it. If someone gives me directions, I just don't remember 2 lefts, 2 rights, etc, but instead I visualize a map in my head with lines drawn like you would see on the directions for Google or Bing maps.
Maybe everyone does this and I am just unaware. Some people associate colors with numbers (Urs) and perhaps use them as a learning/memory too, too.
