Colors of Squirrels Squirrels are brown and sometimes grey. Sometimes they are both. This sounds kind of wierd, but look closely next time you see one. Sometimes you are far away and think it is brown, and then you get close and it looks kind of grey. Here is how that happens. There are hundreds of colors in the unviverse. When you are far away your eyes couldn't tell the difference between all of them, it is a small difference! Each hair on a squirrel is a little bit different. There are many hairs on a squirrel. Some are brown and some are grey and that is why its hard to see.
