I always keep two lip colors around when I’m going to work — a red and a pink. These can be any red and any pink, whatever works best for your skin tone. I just like having both around, because different outfits and occasions will call for different looks. A red lip with a plain black sweater does very different things than that same sweater with a pink lip.
It’s a ton of fun to play around — what kinds of lip color do you like?
