![]() ![]() Some detect the red light (about wavelengths of 700-600 nm), others for the green ones (wavelengths of 550 nm) and others for the blue ones (detecting radiations of 450-400 nm). Primary colors of light (RGB model), additive synthesisīiologically, the human eye has cells called cones, possessing up to three types and each characterized by being sensitive to a particular type of light. However, the normal human eye can only perceive them through three types of receptors called cones, corresponding to the trichromatic theory, so that the waves it appreciates are mostly limited to red lights, green And blue.Īlthough the maximum sensitivity of the cones does not occur exactly with these colors, they are chosen because they allow to stimulate them in an almost independent way, providing a wide range of colors. More than a fundamental property of light, primary colors are part of a biological concept based on the physiological response of the human eye to light.Įssentially, since light is a continuous spectrum of wavelengths, the number of existing colors is almost infinite. There are several theories that classify primary colors in different ways, such as the traditional one that has always been heard and taught, but in addition to this there is also the modern theory of color which distinguishes between light colors and pigment. From these colors the chromatic circle or colored wheel is constructed. It is called primary colors to those basic colors that can not be obtained by mixing any other, which is why they are considered absolute, unique and unique colors, very different from each other because they lack common shades.īy means of these it is possible to mix a greater range of tones and to create new colors (secondary or tertiary). Yellow + Green = YELLOW-GREEN Primary colors When you mix a primary color and its closest secondary in the basic color wheel, new blends called tertiary colors are created. By mixing the primary colors the secondary colors are obtained. ![]()
