Hey, for some reason, the getAvatarColor() function didn't seem to be returning colors properly (Maybe I used them to stylize incorrectly?). I was unsure about how to fix this and didn't want to go looking to make any changes since it's not quite relevant to the issue, but wanted to let you know. This issue persists in my other issue for this week, as well.
