I know that, but how the oxygen in the blood make oxygenated blood bright in colour?

Very good question!
Fully saturated hemoglobin does not absorb light in the same way that unsaturated hemoglobin absorbs light. A hemoglobin fully saturated with oxygen absorbs every color but red – therefore red is reflected and that is the color that we see. This is why well-oxygenated blood looks red.
I hope this explains your additional comment. If you want more detail and if you have a decent background in Chemistry, Email me and I'll be glad to assist you further.

When the hemoglobin molecules in a red blood cell (RBC) take on oxygen the color becomes bright red.

When hemoglobin, the molecule in red blood cells that carries oxygen and gives its red color, is bound to oxygen it is bright red.

If memory serves correctly; oxygenated blood is brighter red from the iron in hemoglobin(eg. arteries). Deoxygenated blood is deeper red because of carbon dioxide interacting with the iron(eg., veins) Example: rust (Iron oxide) is red...

when a red blood cell is filled with oxygen, it is bright red, but when it has more carbon dioxide than oxygen, the color darkens....

due to presence & absence of oxygen,respectively,in the haemoglobin.

because it contains hemoglobin
