1, equivalent red light+green light = yellow light, which is complementary to blue light;
2. Equal amount of red light+blue light = magenta light (also called magenta, that is, light magenta), which is complementary to green light;
3. Equal amount of green light+blue light = green light, which is complementary to red light.
If one of the three primary colors is equal to other colors to form white light, these two colors are called complementary colors. Complementary colors can block each other. So we can know the following three pairs of complementary colors: yellow and blue, red and cyan, green and magenta.
Extended data:
The 12-color phase ring consists of primary colors, secondary colors and primary colors. The three primary colors in the color phase ring are red, yellow and blue, which are evenly matched with each other to form an equilateral triangle in the ring.
The secondary colors are orange, purple and green, forming another equilateral triangle between the three primary colors. Red orange, yellow orange, yellow green, blue green, blue purple and red purple are three colors. Tertiary color is a mixture of primary color and secondary color.
Ordered color rings allow users to clearly see the results of color balance and harmony.
