Really cool project. Out of curiosity, what made you choose red for happy?

It was a while ago so I don't remember. But if I had to guess, probably bc hearts are red and they're associated with liking things online

really cool!

thought I would share that usually I associate yellow with happy and red with angry.

Yeah, that makes sense since smiley faces are yellow and red is traditionally an angrey color. Maybe I should have done that.
