色彩设计学（Color design） 7 、 color design First, the physical properties of color 1, light and color 1) concept: in fact, different wavelengths of light stimulate the visual response of human eyes. Light is the stimulus of color sense, and color is the result of visual organs. 2) the physical properties of a color are determined by the wavelength and amplitude of light waves. The difference in length of light determines the difference in hue. Amplitude determines the difference between hue and shade. 2, object color 1) when light shines on an object, absorption, reflection, transmission and other phenomena occur. The color of a transparent object is determined by the color of light it passes through; the object of an opaque light depends on the reflection and absorption of various colored lights of different wavelengths. 2) the degree of saturation (purity) of an objects surface color depends on the amount of light absorbed and the amount of surface reflected light, which is actually related to the properties of the surface of the object. 3. Color rendering of light source Natural light, incandescent light, daylight lamp, and color light can affect the color of objects. Two, color classification 1. achromatic lines Of black, white, and black and white shades of gray. 2. has a color system Red, orange, yellow, green, blue, purple and other colors. Three, the basic characteristics of color 1, hue Exactly indicate a color, color, or other name. 2, the purity (chroma, saturation) The degree of purity of a color indicating the proportion of colored parts in the color. 3, brightness Brightness of color. Two cases: 1) different brightness of the same hue. When the same color is added into different colors or black and white colors, the brightness will be lowered. 2) different colors of different brightness. Yellow is the highest, blue and violet lowest, and red is the middle lightness. Four, color mixing 1, three primary colors Any color of the three colors cannot be produced b
