The traditional color wheel model dates to the 18th century and is still used by many artists today. This model designates red, yellow and blue as primary colors with the primary–secondary complementary pairs of red–green, blue-orange, and yellow–purple.
In color wheel theory, a complementary color pair contains one primary color (yellow, blue or red) and a secondary color (green, purple or orange). The complement of any primary color can be made by combining the two other primary colors. For example, to achieve the complement of yellow (a primary color) one could combine red and blue. The result would be purple, which appears directly across from yellow on the color wheel. Continuing with the color wheel model, one could then combine yellow and purple, which essentially means that all three primary colors would be present at once. Complementary colors can create some striking optical effects. This is where POPWHITE "POP" Technology is represented in the color wheel, where purple plus yellow equals WHITE.
And now for the long answer (for our fellow beauty geeks): Conventional dental whitening products rely on some form of peroxide; however, when peroxide breaks apart stains, it contributes to changes in enamel structure and may cause sensitivity. POPWHITE products are peroxide free and whiten teeth using a combination of color wheel theory, premium ingredients such as xylitol and coconut oil that support dental whitening.
