when its in the veins its blue normally its red/darkred.

Blood is only blue when no oxygen is reaching it. So when in your body it is always red ^^
I think.

Its always red. Veins are blue but the blood is still red.

Blood is red because blood cells are red, and blood cells never change color.

I hope that wasn't sarcasm...

The red blood cells are only in your blood coming out of the heart... in arteries... when the blood is being pumped back into the heart they are goin thru veins, after theyve dropped off the oxygen to different parts of your body. so veins are blue and the blood inside is blue but in arteries they are red and always are...

Its red sometimes dark red.
I got a blood test and thats what colour it was.
Also if its not blue because in hospitals they inject blue/black dye into peoples veins and arteries to see if they are blocked. And if your blood was blue why would they use they same colour dye?

red, put your hand up to a light and it glows through red.

When blood is inside your body, it is blue - hence why your veins are that dark blue/purplish colour. It's blue as there's no oxygen, and therefore no haemoglobin.

When your blood is out of your body - say you had a cut - it meets with oxygen, and the present haemoglobin causes it to turn the redish colour you would always expect it to be.

It's a scientificly proven fact, that blood is blue when not in contact with oxygen (in the body).
