Why do veins appear the color they do under the skin (when human blood is red)? This is a great read from The Conversation (a nonprofit organization that uses fact- and research-based journalism).

@LoveislandbloxyburgHuman venous blood is often mistakenly thought to be blue because it looks that way through the skin, but it is actually dark red, turning bright red when oxygenated. Scorpion blood is scientifically different, actually showing a color change based on oxygenation.
