These colors come from your hair color. Be sure to look at the lightest and darkest parts of your hair, including your eyebrows. You may notice your hair is off black, brownish black, or even a blue black. Maybe it's mahogany, cool dark brown, or charcoal brown. Notice if the tone is warm or cool and match this tone in your basic colors. These basic colors act as a background and need touches of other colors or metals to give them vitality. Wear these when you want to appear relatively quiet, understated, and stable.
