Usually the cut is what needs special attention when it comes to certain face shapes not the color. The good news is, an oval face shape is considered to be the most flattering. Any color you choose that compliments your skin tone would be great. Post a picture for better advice as to which tones and colors would be best.

What is your natural color? You can do any color for any shape face.....certain cuts can be better for different face shapes but color doesn't matter. It's best to pick a color that complements your skin tone.
