Persoanlly I think stila offers the best colors as a professional line. They have a lot of vibrant colors along with some great neutral tones. Plum is a very unique color which is very hard to find from other lines. The color itself is somewhat mauve/pink/purple in one. It's a little sticky but offers great medium coverage. If you put lip balm underneath, it'll smooth out the texture and gives you a more even finish. Although the price is very high, the color is also hard to beat.
