NYX's round lipsticks offer a super wide range of colors, and are very affordable as well, ranging from $2.50-$4.00 depending on where you buy them.

Those swatches are just of the ones I own, there are many more. You can find these lipsticks at nyxcosmetics.com or cherryculture.com. I found mine in a Ulta store. I would suggest, if you want to purchase these online, to google a specific color in images, because often times the color swatches in the online stores are not accurate. And one last thing, sometimes you can get very good deals on Nyx cosmetics in Ulta, because they often have buy one get one half off or buy 2 and get one free, you just have to keep an eye out for those types of deals.
