Recently, I was in the CozyChat, and I mentioned my red-green colorblindness. Afterward, I was thinking about it, and remembered an interesting website that shows a simulation of how people like me see the world. Here's the link:
Also, since I often get questions from people about red-green colorblindness, here are a few articles by Daniel Fluck about it. If you ever wondered exactly what "red-green colorblindness" mean, here's your answer. I promise, the articles are short.
A little more info on myself (for those who care): I am green-weak, and the technical term is "Deuteranomaly" (for those on the Colors of Confusion article, select Deutan Lines). Normally, I can try to distinguish colors I find similar through the brightness level, but this doesn't always work.
Feel enlightened with your new-found knowledge!
