If blood is red, then why do your veins look blue? The answer might surprise you."
"Many people think the blood inside veins is actually blue. But that's completely false."
"Human blood is always red. Oxygen-rich blood is bright red, while oxygen-poor blood is a darker red."
"So why do veins appear blue?"
"It's because of the way light interacts with your skin. Blue light doesn't pe*****te the skin as deeply as red light, causing veins beneath the skin to appear blue to your eyes."
"In reality, if you could see the blood directly inside your veins, it would still be red—not blue."
