The variety of colors is endless, colorful, but there is a certain intrinsic connection between the colors, and the color of the paint is also. In addition to the special functions of protection against corrosion and mildew, electricity, noise reduction, etc., the main function of the paint is to decorate the home with a colorful life. However, since each color has its own characteristics, it has different effects on people's visual, psychological, and physiological aspects. Let's take a look at the basics of paint color and how to color.

The basic concept of mastering color is the basis of paint coloring. Each color can be determined by three parameters, namely the three properties of color: hue, lightness and chroma.

1, hue

Also known as color, color, refers to the difference between color and color, hue is the most basic feature of color, it is determined by the spectral composition of light, because different wavelengths of color give people a different color perception, therefore, can use monochrome The wavelength of light represents the color of light. This property allows us to describe objects basically as red, orange, yellow, green, blue, and purple.

The seven primary colors said: Later generations mistaken Newton's examples of red, orange, yellow, green, blue, enamel, purple and other colors to suggest that he proposed seven primary colors.

The six primary colors said: Verner (When Verner) went to Newton's seven colors and thought that red, orange, yellow, green, blue, and purple were the six primary colors. The Swiss color educator, Johannes Itten (1888-1967), based on the three primary colors of P. O. Runge's color-receiving material, added the secondary color of the middle, into red, orange, yellow, green, blue and purple primary colors.

The five primary colors said: The ancient Greeks used white, yellow, red, blue and black as the five primary colors.

The four primary colors said: red, yellow, green, and blue colors are composed of red, green, yellow, and blue. Herlin suggested that the NCS color system adopts this.

The three primary colors said: "Leoité du Coloris" (1756) by Jacob Christoph Le Blon (1667-1741) may be the first to propose the theory of the three primary colors.

Physiological primary colors red, green, purple

Color three primary colors red, green, blue

Color three primary colors magenta, yellow, blue

2, brightness

It refers to the light and darkness of the color, and the brightness is usually expressed by the reflectance. The same color will produce different brightness due to the difference in light intensity, and there will be similarities and differences between the colors in the same color. The human eye has different visual sensitivities to different colors, and different colors have different brightness perceptions when the reflectance is the same.

3, chroma

Also called saturation, it refers to the purity of color, also known as the degree of vividness of color. Saturation depends on the ratio of the color component to the achromatic component in a certain color. The larger the color component, the greater the saturation; the larger the achromatic component, the smaller the saturation.

Bright color: solid color plus white lightening

Dark color: solid color plus black to dark, also known as color

Cloudy color: solid color plus gray to intermediate color

Clear: Both clear and dark colors are clear
