How funny, my DH prefers me without makeup because I look more "me" then...though when I do take the time to do something special with all the lovely colors I have, I get compliments followed by "So, wanna go out somewhere?" It's my secret weapon for when I don't feel like cooking dinner.
I have pretty light skin and my hair is normally red (though it's naturally light ash brown). I love to play up my eyes so I usually stick to more subtle lip colors, plus my lips are a slightly unbalanced shape (thinner on the sides on the top lip) and dark colors tend to accentuate that, so I avoid them unless I feel like messing with lip liner.
Others more familiar with a wider range of SN lippies may have better suggestions, but here's my go at it:
Gold Blush was the fist SN lippie I bought, I still love it, it's very subtle with pretty gold sparkles. You could try Mimosa (peach golden shimmer) or Precious (pink golden shimmer). The shimmer in them both make my lips look plump and the colors aren't bright on my lips. Same with Gleaming (gold shimmer) and Sparkle (white shimmer). They are great over some of the lippies I've ordered in the past that were too bright or the wrong tone, plus they work well on their own for just a boost of shimmer with no color. Sparkle makes my lips look plumper and more balanced than any of the others, I adore it! I like Caramel and Centerfold too, they have a glossy sheen but aren't shimmery. They make great nude lip colors though! Sweet Nothing is my "darker" color if I want something cooler than the others, it's sheer enough not to overpower my lips. Hope that helps!
