What colors can red and blue be made of?

The color that appears after red and blue is purple or magenta.

According to the different proportions, although red and blue can turn purple in theory, the composition is uncontrollable, good. If it is one to one, it is pure purple, light red and light blue are lavender, and pure red and pure blue are pure purple. If there is a lot of red, it is reddish purple, and some people say it is pink. In short, different purples will be adjusted according to different proportions.

Red, yellow and blue are one of the three primary colors, and different mixtures of the three colors present colorful colors. When red and blue are mixed, the color becomes purple, but different proportions of red and blue produce different purple:

A lot of red and a little blue can bring out red and purple, and a lot of blue and a little red can bring out blue and purple. The colors of components that gradually change from blue to red are: red, reddish purple, purple, purple-blue, blue-purple.

Tricolor color matching technique

1, color lightness:

Methods to increase brightness: add white or dilute with water. White space is the highest brightness in the picture, and it will be lower than white space as long as there is color.

Ways to reduce brightness: As long as the mixed colors will reduce brightness, each overlapping color will also reduce brightness, and add black or complementary colors.

2. Chromaticity of color matching:

The closer the distance on the color circle, the higher the mixed chromaticity of the two colors, and vice versa.

Methods to reduce chromaticity: adding white, black, complementary color or diluting with water will reduce chromaticity.

3, color tone:

Add white, dilute with water and add black. The brightness of the first two increases, while the chromaticity of the three will decrease, but the hue of the three remains unchanged. In other words, its position in the color circle remains unchanged, and only the light and shade and chromaticity are changed.

Adding a small amount of complementary colors reduces the brightness and chromaticity, but the hue remains unchanged. If excessive complementary colors are added, a new hue with complementary colors as the main color will appear.

After any two colors are mixed, the position of the new hue in the color circle is close to the side with a large proportion.
