Cats' eye colors can be broadly categorized into blue, yellow, green, amber, tan, and brown. In short, cat eye colors are incredibly diverse, largely influenced by breed and genetics. However, some breeds have typically fixed eye colors; for example, Ragdoll cats usually have blue eyes, and British Shorthair cats often have copper-yellow eyes.

Actually, these are all fairly normal colors. Once we understand them, we won't think much of it. A cat's eyes are one of the things that highlight its charm. If we look closely at a cat's marble-like eyes, we'll feel like we're "lost" in them.
