What color would your blood be if your skin was blue?
Answer 1:

A better question is what color would your skin be if your blood were blue.

The answer is that it doesn't change much. Squids and octopus do have blue blood, but their native skin color (which is usually a pale white or deep red) isn't much affected by the color of their blood. It's only when your blood rushes to the surface (blushing) that the color of your blood changes the color of your skin.
