itch.io

I went into the config and I saw a bunch of things (after I learned I can turn the sounds off) and I wanted to test other things. I tried to change the goose from white to black. and I looked up the code for black wich for the first result seems to be #000000 so I tried it, I clicked save, and it didn't work. so I went back in and I set custome colors to true and clicked save and still didn't work. idk what I'm doing so can anyone tell me what I'm doing wrong? I think it would be neat if I could change it's main color at least.
