If you cross your eyes so that the two + overlap, you may be able to see the colour called "yellow-blue".
For each row, stare at the left image for 20-60 seconds, then suddenly change your focus to the center image. These specific types of colour are known as chimera colours.
All of these colours are known as "impossible colours", as they cannot be percieced by our eyes under normal lighting conditions, or in some cases, at all (yellow-blue and red-green are "seen" due to the visual cortex of the brain being confused).

Highlight the text if you can't see it. My favorite color is #000000. My laptop is a jet black Alienware. The lights are white, and white only. My computer screen is set to grayscale. (That last one isn't true, but I have done that with previous computers) I like the aesthetic of Razer, the black is on my Razer Phone and Naga Hex V2. Most days I wear black jeans and a jet black tee. I like black and I cannot lie.
I like Purple and Black as well.
Speaking of, sellout moment: Go fund Dino Run 2! Pixeljam runs lean so it would be great if you guys could help make this nostalgia trip a reality. https://discord.gg/pixeljam
