When we look at a leaf, we see the colors of light that are reflected off its surface. how does the relatively low flow of oxygen in green light?

Usually, the color of leaves is green as they contain chlorophyll and it's reflecting the color of chlorophyll but when we look at a leaf, we see the colors of light that are reflected off its surface because chlorophyll in plants gives the leaf its color. The chlorophyll can't absorb oxygen, that is why it causes a reduction in the flow of oxygen and therefore the chlorophyll is green and reflects off green light.
