'Smatter of fact, I have several shades of orange in glosses, varying brands. I've always loved it, as I have very fair skin, and reds I like to do can often make my skin look like its gone up in flames--I love to wear the reds in the winter, when the cold keeps me a little paler, but I do mostly oranges and pinks in the summertime (I stick to glosses in the summer, vs actual lipsticks, because they're lighter and make me feel all smiley

)
I'm also kind of obsessed with matching my lips to my nails, which are pretty much always an orange or pink this time of year (huge fan of OPI's Cajun Shrimp... 
)
Alicia, you're right. The best "oranges" actually have a more peachy, coral kind of look to them, and it's surprisingly flattering on a wide range of skintones. One of those things that you think "Omigosh, I could never get away with that!" but will be pleasantly surprised when you try it on... With your dark hair, it'd be gorgeous on you!
