lol thank you, I've been using the user-created night mode layout: -Night Mode- Shengui Guo Custom CSS [v2.0] with the dark backgrounds I've been noticing more stray marks. I'm wearing this body blush now and I could see a faint pink mark hovering near my avatar's face and I was like "hmm what's that?"
I imagine the artist used the circular shape of the brush to place the blush marks on the body, but didn't erase what got outside of the body all the way.
