If you are born with fur or hair (like, say, your large shell-less mama) and you have red or pinkish tinted eyes, you might be an albino.
In fact, even if you were born with a shell and your eyes are red or reddish, you might be an albino.
Albino beings look the way they do because of a malfunction in pigment production.
But some shelled beings have red eyes and are not albino.
For example, let’s say you are a rescued 3-toed adult box turtle and you have the trademark 3-toed box turtle solid olive-colored shell.
Your face is quite colorful, however, and your eyes are a bright, vibrant red.
In the box turtle world, this means you are a boy!
While lady 3-toed box turtles tend to have deep brown eyes, manly and masculine 3-toed box turtles are much more likely to have bright red eyes (or sometimes orange eyes, which is also a great look).
