Sanyuan of color: hue ( Hue) : is the color difference between features, decided by the main wavelength of light. Lightness ( 暗的) : the feeling of the human eye to color light and shade degree. Chroma ( Chrome) : the feeling of color purity, therefore is also called the 'saturation'. Resolution of the human eye to color is related to the wavelength of light, the eye in the feelings of the sensitivity of the visible light wavelength range all different color is difference, the human eye to yellow green light wavelength region is the most sensitive, the human feelings which wavelengths of light more comfortable.
the color of color mix the laws of the same color spectrum: object color and reflection ( Transmission) The spectral power distribution of the light, but not one to one correspondence, which leads to the many of spectral distribution of different light also can cause the human eye the same color. Same color spectrum phenomenon is caused by human eye the resolving power of low, same color spectrum makes it easy to mix colors.
the three primary colors ( 三个主要的颜色) : any color can be by no more than three primary colors, proper mixed in certain proportion, primary colors were independent of each other, that is either primary colors cannot be produced by the other two primary colors mixed.
color mixed three rules: low complementary law: A + color A complementary color = white low intermediate law: any two complementary color mixing = low middle instead of law: such as: color A = B; Color C = D; Is: color A + C = color B + D additive method ( 加色混合) — Light hybrid method definition: by two or more light adopts the method of direct or indirect mix between the synthesis methods of new colours. Light color: CIE stipulated; Red light, 700nm) , green, 546nm) And blue 435. 8 nm the subtractive ( 减色法混合) — Pigment hybrid method definition: according to the white light is light and color characteristics of selective absorption, use two or more ink absorb it different colours, and then the method to get the required color. Pigment three primary colors, green, magenta, yellow, respectively is the primary colors red, green, and blue light color.
