Dispatch of Chinese paint net / before we are studying method of coating mix colors, should understand the common sense of respect of a few color above all. The color of the object in nature is Protean, the person can see the color of the object, because the radial illuminate of illuminant is on the object,be, ray radiation is on the object, smooth radiation energy action the result at the eye. Do not give off light the color of the object is appeared to come out only by the ability of the light when shooting, the color of the object is decided by the circumstance that the light is reflexed on the object and absorbs. An object presents green below sunlight, because this object is main,be the wavelengh of green limits of Bai Guangzhong reflection comes out, and spectral other part is absorbed by it, if observe below sodium smooth lamp this object does not look to go out is green, because sodium is done not have in smooth light,the component of green light can be reflexed by it, here can see, follow illumination spectrum component and the visible color of the object changes. If an object reflexes the light that shoots completely, so this object we look is white, if it is absorbed completely,project in the light above it, criterion this object looks is black.
Color cent is blame color and color, be not color is to show black, white and this is both between the gray with different depth, the is not color reflectivity on white black series represents the lightness of the object. When reflectivity is taller, be close to white, lower when, be close to black. Chromatic series is to point to all sorts of color besides white black series. What spectral and different wavelengh is all sorts of color in the expression on the vision is tonal, be like red, orange, yellow, green, green, violet etc. Should say exactly to be clear that some is planted color, must consider 3 major attribute of color, namely tonal, degree of saturation and lightness, this 3 person the total effect that unites in the composition in the vision. Tonal it is to point to prevail with which kinds of wavelengh in object catoptric light will decide, different wavelengh produces different color feeling, tonal the main feature that is decision color essence. The degree of saturation of color is the bright degree that points to a color. Tonal, lightness and degree of saturation are 3 major attribute of color, blame color has the difference of lightness only, and harmonic without color degree of saturation these two attribute.
The mixture match colors of coating follows principle of a kind of subtractive process, thirdly primary colors is yellow, green, violet, their each other complementary color is orchid, red, green. Alleged complementary color namely two kinds of shade mix by certain proportion get white shade, gules complementary color is cyan, maize complementary color is orchid color, green complementary color is purple.
Maize = white - orchid color
Purple = white - green
Cyan = white - gules
