Kidding. I would never. I'm not cool enough.
Buuuut I can do it on Tod! On her eyes at least. I think she'd kill me if I secretly dyed her hair while she was sleeping. But for a fun night out, here's a really last-minute look.
|Without flash, so you can see what she actually looked like|
I wanted a really messy, watercolor-y look so I used all fingers and a 224 brush. I also marbled two lipsticks together to get that sort of tie-dye feel before topping with a gloss. Let me know if you'd like a proper tutorial and I'll have it up by Monday!
EDIT: Tutorial is here!
