Well, most people here will probably tell you that your natural hair color is a good compliment to your skin and features. You can look at your coloring and skin type (clinique has a good quick way to evaluate this and suggest products https://www.clinique.com/templates/u...in_report.tmpl
here) and then look at warmer hair colors (chestnut, red, strawberry blonde) or cooler (black, brunette, ash blonde) depending on your coloring. As far as your features are concerned, you can style hair depending on your face shape (i.e. if your face is round try long layers and a bit of lift at the top of the head to create length, if your face is long shorter layers like long bangs swept to the side, with more fullness at the sides of the face). There's plenty of more beauty-related websites online for lots of this stuff. I did a google search for warm or cool coloring (usually a good place to start) and got tons of results.
