What's the favorite color of bees?

In nature, the colors of flowers are really varied, but the most common ones are red, yellow and white. In fact, the color of flowers is the result of natural selection, depending on the insects attracted to pollinate them. Honeybee is one of the main insect-borne insects in nature. Let's take a look at what color bees like best.
1. What color do bees like?
 The favorite colors of bees are yellow, white and blue, especially yellow is the most attractive to bees. This is why plants with bees as the main pollinating insects in nature have yellow flowers. For example, the most common rape flowers, sunflowers and so on. At the same time, bees are also very sensitive to white, such as the most common locust tree flower, plum tree flower, pear tree flower and so on. In fact, bees' choice of color is the result of evolution. Because the general yellow flowers, white flowers are the symbol of the great source of honey.
2.Can bees distinguish colors?
 Bees have a pair of compound eyes, each of which consists of about 5000 small eyes. Each small eye has a light collecting system and a photosensitive system, while bees also have three single eyes to cooperate with the compound eye to feel the change of luminance, the direction of the light source and so on to form a rough image. Therefore, bees can distinguish between 650 ~ 530 nm (red, yellow and green), 510 ~ 480 nm (blue and green), 470 ~ 400 nm (blue and purple) and 400 ~ 300 nm (ultraviolet zone).
3. Are bees really color-blind?
 Although bees can distinguish colors, they can only recognize yellow, cyan, blue and purple light. White in the eyes of bees is a mixture of yellow, cyan, blue and purple. At the same time, bees are color-blind to red light, so there is no difference between red and black in the eyes of bees. Orange, yellow and green look the same to bees, and bees can see ultraviolet rays that people can't see, and can accurately distinguish ultraviolet rays from different shades of white and gray.
4.How do bees find flowers?
（1） Flower scent: there are a pair of antennae on the head of bees, and there are particularly sensitive olfactory organs on the antennae. Many plants give off the scent of flowers when they bloom, so bees can smell the fragrance of all kinds of flowers with the help of their antennae and find out exactly where the nectar is.
（2）Design and color: bees do not fly in a straight line when looking for honey plants, but use the "Zhi" shape to find them while flying. But bees have different preferences for flowers and will swoop on them when they find their favorite yellow, white or blue flowers.
