In the picture below are represented both models, left additive, subtractive right, and their tight relationship. This color model is subtractive, ie, the pigments absorb certain frequencies of the spectrum while reflecting the rest. In this model it is paper, when white, which produces white, while the black color is emulated using an extra ink because of the saturated mixture of the three primary colors produces a dark brown color. This model uses three inks, which mixed and printed, can reproduce the widest possible range of colors: cyan, magenta and yellow. This is a color model radically opposed to the previous one because the light absorption by the material follows different rules from the perception of light by the eye. The behavior of the paint, ink or pigment mixture is reproduced using the CMYK color space. It is an additive model, which means the sum of the three primary light produces white light (more light more color), while its absence produces black. The color property of the light emitted by the sun or an artificial source, reflected and received by the optic nerve, is emulated by using the RGB color space. This model is based on the sum of three monochromatic lights: red, green and blue, from which you can reproduce the light spectrum. Designers mainly use two spaces or color models, basically, though not the only ones available. These models define how computers simulate the color. There can`t be a design blog that does not have a publication about the color theory, whether viewed from the standpoint of the composition, selection, space, or psychology. Since the data available on the web is much i’ll try to be very specific.īefore you start talking about the color and artistic theory i should explain what and how we perceive color in our computerized world.
