> In short, color detection when looking at small things, deciding what color an item is when it's so small that only the color difference signal at the edges can make the determination, is worse for color-blind people. Even though the colors are easy to distinguish for large objects, it's hard when they get small. Like the author of the article I am partially red-green colorblind. I found it particularly Illuminating to understand why the amount of colour makes a difference in the ability to distinguish between them. It's someting that I have repeatedly observed on my own, but I could never properly explain.
