Then when you are at the store, try to look past any items that are in your worst colors, and look for your best colors. Always ask if something comes in a different color, sometimes there will be other colors online or in the back stock of the store.
The book I use in color consultations is called Color Me Confident: Change Your Look - Change Your Life! by Veronique Henderson and Pat Henshaw. It uses a more thorough method than the "Four Seasons." It considers hair and eye color as well as skin color, and has more categories than just warm and cool, like some methods.
I give one-hour color consultations in my home in downtown Bellevue for $40. Contact me for more information.
