hello. today we will speak about colorimetry. by nature we are able to identify three basic colors. they are defined primary colors and those colors can be found pure in nature. primary colors are those colors through
alfaparf milano hair color chart, which we can make all the other colors. do not forget that the light color is white and white light then creates all the other colors that then we will use. however, the white light
is associated with a real concept of coloring, which helps us a lot in our job, that will define what may be the primary colors. so, the primary colors are yellow, blue and red. the infinite combinations of primary colors allow us to get all the other colors. if i associate the primary colors with each other, i'll get the other three colors, the secondary colors. yellow and blue in equal parts give me the green; red and blue in equal parts
give me the purple; yellow and red in equal parts give me orange. these colors combined together are the primary and secondary colors. this classification will help us a lot when we will color our customers hair. so this is theory, but we will need to apply it in practice. combining a primary color with a secondary, we also get the tertiary colors. if i join the primary color yellow and
the secondary color green, i get the tertiary color yellow-green. the green color combined with the blue will give me the blue-green; the blue with purple will give me the blue-purple color; red with purple will give me the red-purple color; red with orange creates the orange-red and orange with yellow will create the yellow-orange. have you ever painted at school with watercolors? the colors combinations, for us, are the same thing
because the combination of these primary colors allows us to get all the colors we want. as it happens in nature, the same thing will happen with the hair, when we're going to associate the colors that will allow us to compose all shades of color that we want. now we speak about the association of our colors. if we mix into equal parts yellow, red and blue will get the gray that we will define a neutral color.
when these colors we'll be adding more and more, we will get the black. then we have the gray scale to obtain the black through the combination of equal parts of yellow, blue and red. it is also important to define complementary colors. what does it means? when i want to neutralize a color, and this happen very often in hair coloration, so i want to remove excess color, i'll have to use its opposite color.
let's see how: in this slide we can find the concepts about opposite colors. for example, if i have the blue color and i want to neutralize it, or not allow it to give the blue transparency, i have to use his opposite color which in this case is orange. orange in fact is composed by yellow and red equally so equal parts of yellow, red and blue, united together are neutralized and get the grayscale. we can obtain all this with the same rule:
if i want to eliminate the yellow i will use its opposite color or the purple, composed by red and blue in equal parts. yellow, red and blue in equal parts will always give the grayscale. then we will have an indefinite color that we will consider neutral. this is the fundamental color classification starting point. this is the first fundamental step through which we can begin to initiate a coloring process. colors can also be divided in two categories: warm and cool colors.
the cool color for excellence is blue; we will define cool colors all the colors that have the prevalence of blue. the blue color is the only primary cold color that we identify in the classification of the primary colors. mixed with another color, the blue will give a cool tone to the color obtained. red and yellow instead are two hot primary colors; red mixed with another color will give a warmer tone to the color obtained while yellow,
mixed with another color, will give a more light and bright result. as you can see we are starting to analyze the color perception; so we leave behind the technical scheme of coloring and we begin to work on the concept of sensations. so i said that the yellow gives brightness, the red gives us heat effects, the blue cold effects. we have to give our customers these colors associations
and color perceptions. another fundamental concept, in the colors choice, is the color combination, that is when we mix two colors. we can have the concept of simultaneous contrast that is associate together two types of colors that can give us completely different effects. we can have a consonant contrast and a dissonant contrast. we have a dissonant contrast when we associate a cold color to warm color, for example we associate purple to yellow.
the effect will be completely dissonant and colors will enhance each other. if we associate two warm colors, such as orange and red, we create a consonant contrast; in this case the colors will attenuate each another.
