I like a good nude lip.
For some reason it seems difficult to find a nude lip color that I like, that doesn't end up getting discontinued.
I love bright colors in the right setting. A red lip can look great any time of day. Now that its starting to get cooler, something like a berry or fuchsia lip is really nice. Orange is more of a spring summer color, but that can look really good. These are more wearable than things like green, blue, or purple. These can look good in the right setting though. I would wear a purple lip to the club, even if its not winter. You can get away with more dramatic makeup during the evening than you can during the day. When it comes to work though, you want to be more boring and basic than usual, just because its more professional. I wear the same basic makeup every day to work. Its boring, but it takes me only a few minutes because i do it so often.
