PLEASE READ! This project may cause seizures in some people. To avoid any seizures, only press 3 and 4 on the keyboard. Keys 1 and 2 will flash between blue and yellow, and red and green very quickly. Do not press keys 1 and 2 if you get seizures. I am really not trying to get taken down. This project may show you some of the impossible colors. These (m) colors include bluish yellow and reddish green. Don't be afraid if you can't see them, because most people can't. Pressing the 1 key will flash blue and yellow, and 2 will flash red and green. Pressing and holding 3 and 4 will have blue and yellow, and red and green, so stare cross eyed at the white crosses.
I saw a video by The Action Lab called "Why There Are No Bluish-Yellow Crayons: The Forbidden Color Experiment", so I decided to see the color for myself. I looked up the most common impossible colors and put then into this project.
