what is the true color of blood? I had a discussion that real blood is blue before oxygen hit it

Blood in your veins is blue because it is de-oxygenated.
Blood in your arteries is red because they carry oxygen to parts of your body via blood.

Blood is red, whether it is oxygenated or de-oxygenated. Oxygenated blood is bright red. De-oxygenated blood is dark red to redish purple. The veins (which carry de-oxygenated blood) appear blue due to an optical effect caused by the way light penetrates the skin.
Blood is red because it carries the protein hemoglobin which contains iron. Iron combines with oxygen and appears red. Since gemoglobin does not completely deoxygenate, venous blood still looks red.
