Also, when your blood is oxygenated and it's on its way from your heart it is red, right? But on it's way back to the heart apparently it is blue and not red??? Or is it all wrong??? TA

No, blood is ALWAYS RED.
It has a gray/blue appearance when it is unoxygenated.
Hemoglobin is always red.

The real answer:
Colour of blood varies between fresh red, scarlet red and dark red, to the point where you can practically call it purple. It all depends on what the hemoglobin carries at the time.
As we know, the red blood cells contain hemoglobin, which binds to oxygen at the lung, then circulates in the organism, providing and supplying oxygen to tissue as it goes along. But as it goes along, it also takes up carbon dioxide, a product of metabolic breakdown. And seriously, Hemoglobin are more attracted to Carbon dioxide than they are to oxygen (which explains how quickly a person develops carbon dioxide or monoxide poisoning in an enclosed space).
So basically the blood cells maybe divided into
oxygenated hemoglobin, with oxygen binding to the hemoglobin. They can be found at the arterial system, especially those coming out from the lungs.
meth-hemoglobin, hemoglobin which has bounded with carbon dioxide, giving it a dark red, almost bluish characteristic.
Then they are those found in pathological condition, like carboxyhemoglobin, when a person is exposed to carbon monoxide, and so forth.
But no, blood never turn blue, only bluish.

You wouldn't survive in space long enough to cut yourself. The second you're outside the ship, you'd either turn into an ice cube or fry, depending on whether or not you were directly in the sun.
