This Foundation Tester Kit has revolutionized how youdetermine one's Season. This is a foundation kit made upof eight, 1 ounce jars (the NEW personal foundation kithas eight, 1/9 oz cups) of specially blended foundations.Four of the jars are filled with cool-based foundation, andfour are filled with warm-based foundation. These colorsrange from light to dark. After determining the tonal range of your skin, you thenapply two separate spots of foundation, one from eachcolor side, warm or cool. Then a miracle begins to happen.The foundation that matches your skin tone will seem toabsorb into the skin and the one that isn't correct will siton the surface and either look like a bruise or an off-colorpatch. The right color foundation will look natural andnormal on the skin. This test is especially effective onthose who have a strong seasonal blend. If it is notapparent which color at first seems to be best, let it siton their skin for several minutes while you continue yourtesting with the color drapes. Eventually one of the colorsof foundation will turn in to that mis-matched color. Onceyou have determined warm or cool, then continue to colordrape for the final season within that range. The Foundation Tester Kit comes in a beautifully designedbox that you can proudly display in your own Color Classes.The Kit comes complete with directions on how to use it.When you use this test, many of the questions are answeredas to what color under base you or your client has.
