If the variable "pixel"s value is 1, the left pixel will be white. If its 2, itll be cyan. If the variable "pixel2"s value is 1, the right pixel will also be white, if its value is 2, itll be pink.
The pixel colour saves so when you log into a different account or just refresh the project page, itll be the same as before unless someone has changed it. Took a small bit of inspiration from "r/place".
