Certain red based purples, and the color Passionate. If I ever want to convince anyone I'm being abused, I'll do a look with those colors. It's appalling!
There are shades of purple and pink that just don't look right on me. Most everything else I can pull off to some degree but medium purples especially are just...ugh.
The number one color that doesn't look good at all on me is blue. My eyes are on the grey side of green, and blue clashes horribly with them. I've gotten into the habit of not even wearing blue clothing.
I can't do brown, either. Every time I try to wear brown eye makeup, it ends up looking dirty. :\
i'll wear just about anything, but i don't think i can pull off all-blue or all-purple eyeshadow. i don't really feel right with BOLD red lips, either, but that's probably because i'm not used to them. (i'll wear softer/more sheer reds.)
I cannot wear BLACK e/s, black liner looks great but the e/s makes me look like I was chimney sweeping. I also look crappy in yellows and oranges. Oh and I love the way Club looks but I cannot get it to work, but grey based e/s like Moth Brown look great on me, weird.
Blue eyeshadows look terrible on me. All blue colours look wrong with my green eyes and pale skin. I have to be careful with purples and make sure they're not on the blue side otherwise those can look horrible too. Also brown lipsticks look disgusting on me.. I think it's just because I'm so pale.
For me it more of color combinations. I will never wear sliver ring and sushi flower together again. Some one came up to me asked me if I was ok since I looked bruised.
