Hey there, sorry to bother you even more, but I've got a follow up question. You said working with complementary colors ("opposite sides of the color wheel") might work better, so in general it's easier to distinguish for red-green colorblind people. I've always thought it was especially hard to distinguish red from green in those cases, but red and green are complementary colors. Where did I go wrong here? Is it something I misunderstood from your explanation or is it my understanding of red-green colorblindness that's just wrong?
