What color is the goldfish?

Goldfish is a kind of fish with high ornamental value. Common goldfish are gold, yellow and orange, purple, blue and black, gray and other colors, and various colors are also common.

The color of goldfish also reflects the quality of goldfish, but in fact there are only three kinds of skin cells and pigments in goldfish, namely black pigment cells and orange-blue pigment cells, and these three colors can be mixed to form so many colors of goldfish.

However, it is precisely because of the many colors that goldfish are so beautiful and have such high ornamental value.
