Cat eye color

1. Green: The color of this cat’s eyes is mainly related to the lighter melanin. Cats in cold areas often have this color. Cat eyes, after all, insufficient sunlight leads to insufficient melanin concentration.

2. Tsubaki color: Compared with green, Tsubaki color looks darker, just like a fusion of green and brown.

3. Copper color: When the melanin reaches a very high concentration, this color will appear in the cat’s eyes. It is also a very common cat eye color among cats.

4. Earthy yellow: Among cats, khaki cat eyes are more common than copper-colored cat eyes. The monochrome yellow color in the pupils brings a very close feeling to the cat. . (The melanin concentration is also relatively strong)

5. Yin-Yang eyes: This kind of cat eyes with different colors on the left and right eyes is really beautiful, at least more attractive than single-color eyes. In fact, yin and yang eyes have an official name, called "heterochromia iris", and a very small number of cats will have "multiple colors in one eyeball", which is related to congenital inheritance.

6. Blue: This color of cat eyes is mainly found in white cats and is a rare cat eye color (the eyes of Ragdolls are this beautiful blue). However, kittens’ eyes are all blue, especially when a kitten is about 4 weeks old, its blue eyes look the most beautiful, and they will only start to change color slowly after they are 2 months old.

7. Red: It looks like the red eyes of a rabbit. This is because cats with "albinism" cannot produce melanin in their bodies, causing their eyes to appear this color. If a cat has eyes of this color, cats with blue eyes are even rarer.
