The primary colors, either additive (RGB) or subtractive (CMY) interact with each other depending on their purpose, but there are also harmonies and color chords as the proportions of Schopenhauer balance. When correcting color or interacting with color corrections it is very helpful to take into account these harmonies, both to correct and to look for a possible look. Once explained a couple of basic concepts, to interact with the color wheel must take into account the color harmonies. Also, keep in mind that the eye is responsible for making the mixes of those wavelengths that reach us. In the issue of wavelength frequencies that the human being is able to perceive in color is a small range of color spectrum that I have already explained with the white balance ranging from 380 to 400 nm. When the sunlight touches the object it absorbs some frequencies and other reflects them, which added to the eye gives us the sensation of the color of the reflected waves. Basically when a ray of light touches an object certain radiation of a wavelength are absorbed and others reflected and what we receive is the mixture of those radiations reflected in a diffuse way. This interaction of light with matter allows us to appreciate the different shades and colors of the material, because light stimulates the specific cells to collect the information of color in our eyes (cones, optic nerve.

These are perceived because there is light, without the light the colors would not be seen. All of them have laid the foundations of what was the beginning of the sphere of color and its various methods of measurement.Р вЂќР’В«efore starting a small explanation of the perception of colors. Among the first that began to realize their theories with their classification modes are the Runge sphere, the ostwald solid, the munsell solid, the NCS system or the three coordinate systems (H, S, L). Another aspect is the origin, for example the ultramarine blue, since it was a color in which its material to mix with a binder came from overseas hence its name. Because of these cultural and environmental facts in the denomination of colors there are important variations in their perception and classification, an Eskimo sees many more shades of white than a European, as it has more specific names of white to an African who perceives more nuances of the red for example and in their culture there are more specific names for red.

In the origins of the chromatic systems the problem was the order in which to establish the colors, to organize them with respect to others and to obtain a classification, since in addition the denomination for each color could vary a lot and was far from being exact as for its nomenclature, whether red vermilion or crimson, contains different 'sociocultural' nuances. The purpose of the color wheel, Newton ring or circle of shades is to show all the colors of the spectrum with their transitions, even the Bauhaus put their geniuses to work on their own theories and measurements, such as the color star and others Chromatic 'circles' developed by teachers. These two work more quickly and more effectively than the POPWHITE, but they did cause more tooth sensitivity.The chromatic circle that we know has had many variants and various theorists have elaborated their proposals. On the downside, it's a bit less effective than some of my other favorite whiteners, including Crest One-Hour Express Whitestrips and AuraGlow's Teeth Whitening System.

I have sensitive teeth (and have even used prescription sensitive toothpaste in the past), and I found this to be much more gentle than regular whiteners.

My teeth were never purple-hued, and they definitely looked a little whiter after usage.

I think this is because the purple deposits haven't had a chance to get rinsed away throughout the course of the day.

The product is most effective at whitening immediately following usage.

I found that that there is a hint of purple after doing both, but it fades in about 15 minutes. The purple hue can be gently rubbed off your lips with a washcloth, and can be brushed off your tongue with a clean toothbrush.

The product does dye your lips and tongue.

Throughout this experiment, I discovered a few key things: I decided to give POPWHITE a fair chance and used it consistently for several weeks. The mouth rinse is undeniably a Barney purple, and feels gentle and soothing versus aggressive or painful like some mouth washes.
