Paint color technology, different object color basic principles introduced.

Color varieties change endlessly, colorful, but there is a certain internal relationship between the various colors, paint color is also. In addition to the paint has the protection of corrosion and mold, conduction, noise reduction and other special functions, the most important function is to decorate the home out of the colorful atmosphere of life. However, because each color has its own characteristics, so it has different effects on people's vision, psychology, physiology, etc

. Let's take a look at the basics of paint color and how to color.
Basic knowledge of different kinds of substances about color
1, color of color-eliminating objects
anti-color objects refer to black, white, gray objects, it has non-selective absorption of light light, that is, when light is exposed to the color-absorbing object, the absorbed incoming light in various wavelengths of color is equal; When white light shines on a colored object, the reflectivity is above 75%, i.e. white, the reflectivity is less than 10%, i.e. black, and the reflectivity is different shades of gray in between.
2, colored objects
non-colored objects on the lighting of the characteristics of selective absorption, that is, when light is exposed to colored objects, the incoming light is absorbed by a variety of wavelengths of color light is an unequal amount, some are more absorbed, some are less absorbed. White light shines on a colored object, and its reflected or permeable light not only decreases in brightness but also changes in spectral composition, resulting in a variety of different colors compared to the incoming light.
3, the spectral composition of the light source on the color of the object
when the colored light shines on the colored object, the object reflects the same color as the incoming light. When more than two kinds of colored light are irradiated on the anti-colored object at the same time, the color of the object has a color-add effect. If red and green light shine on a white object at the same time, the object is yellow.
when colored light hits a colored object, the color of the object has a color-detracting effect. On the other way, yellow objects appear red in bright red, green in cyan light, and gray or black in blue light.
4, the relationship between the color and light of an object
un-self-luminous color): the color produced by light of an object is the color that does not glow, such as color tickets, paints, fabrics, etc.
