Unless the packaging specifically states not to use on lips, or around eyes, most makeup products are multi-functional. I use eyeliner to line my lips and fill them in, and I've used blush as eyeshadows and vice versa. My absolute FAVORITE for uncommon colors especially lips color is OCC
(Obsessive Compulsive Cosmetics). I'm not sure what your budget is for makeup, but their lip tars are the most pigmented things I've ever used, and they last you a long time because a little bit goes a long way. They are sometimes difficult to get ahold of, but I purchased a gorgeous bright orange, dark purple, white, and yellow lip tar in the past. They are amazing for cosplay. I third NYX as the cheaper (but still amazing quality) for lips and eyes. The jumbo pencils come in every color imaginable, and they last a while as well.
