Can the red sign be painted with green paint?

The red brand can be painted with green paint.

When red paint and green paint are mixed together, you will get a turbid color, a bit like brown.

Basic knowledge of paint color matching: colors are divided into colorless and colored. Colorless means that there are different shades between black, white and gray, and the colorless reflectivity on the white-black series represents the lightness of the object. The higher the reflectivity, the closer to white, and the lower the reflectivity, the closer to black. Color system refers to all colors except white and black series. Different wavelengths of the spectrum are visually represented as tones of various colors, such as red, orange, yellow, green, cyan and purple.

To explain a certain color clearly, we must consider three basic attributes of color, namely hue, saturation and lightness, which form a unified overall effect visually. Tone refers to which wavelength is dominant in the light reflected by an object. Different wavelengths produce different color feelings, and hue is the basic feature that determines the nature of color. The saturation of color refers to the brightness of color. Hue, lightness and saturation are all colors.

Of the three basic attributes, achromatic color only has the difference of lightness, but has no hue and saturation.

Mixed colors of paints, pigments, dyes, etc. Follow the principle of subtraction and mixing. The three primary colors are yellow, cyan and purple, and their complementary colors are blue, red and green. The so-called complementary color means that two colors of light are mixed in a certain proportion to get white light. The complementary color of red is cyan, the complementary color of yellow is blue, and the complementary color of green is purple.
