Oxygenated blood is bright red. Deoxygenated blood is darker red. When it is seen through the wall of vein vessel, deoxygenated blood appears blue.

De-oxygenated blood is NOT blue. It is dark red. It becomes bright red when oxygenated. The red colour in blood is from the iron ion in the middle of the hemoglobin. All forms of iron are reddish in colour.
Venous blood only appears blueish through our skin because of the way our semi-trasnparent skin either absorbs or scatters parts of the light spectrum.
I've seen venous blood trapped in veins with the skin above removed, and it is dark red.

Human blood color is red, never blue. Oxygenated blood is less red, lighter red, than oxygen poor blood, dark red.

Not really. It's a sort of dark red colour, maybe with a tiny hint of blue in it.

I learned the same thing that blood is actually extremely dark and bluish until it hits O2, then you get the bright red color.
