A satisfying series of random colors mixing. The only unsatisfying part is that you have three seconds to decide whether the result will be pretty or ugly. Or you can just watch. Either way, keep in mind the color on the left is the main color, while the one on the right is the minor color, therefore the result will be affected more by the main color, which is, again, the left color.
Basically I was just thinking of stuff I could do for a project that is really quick to make because I always get bored of continuing projects (I have 86 unshared projects lol)
