What are the three yellow colors referred to

The colors red, yellow and blue are considered the three primary colors of light in color science. In the synthesis of light, red, yellow and blue rays are mixed in different proportions and are able to simulate almost all the colors in the visible spectrum. With the largest spectral range and the least overlap of spectral components between them, red, yellow and blue can be most effectively mixed to produce rich colors. In painting, design and other visual arts, the primary colors of red, yellow and blue are widely used, and through color mixing and blending, artists are able to create colorful images and works of art. The yellow tricolor refers to red, yellow and blue, and is in fact a universal term for the three primary colors of light.

The yellow tricolor combination is particularly common in traditional Chinese culture, and is widely used in artwork such as palace architecture, brocade, paintings, and ceramics.
