I like purple hair too.
One of my best friends in school said I had a fetish for 'purple haired ***' a.k.a. 'PHB fetish' It wasn't till later I realized she dyed her hair purple...
She wants the S.
The S?
Nah I just kinda focused in on the middle. Grey/silver tends to be such a neutral color for me that unless it's front and center I assume it's just background without even second guessing.
This mostly applies to anime style pictures. RL, silver and shiny is all me.
I like...different. Blue, purple, silver hair. I'm not much into body modifications or tattoos, just my opinion. Though none of these things will make or break a potential relationship, depends on the person.
