Transmission, reflection, and absorbtion

[LogicalAcid]

In order for us to see something, the light photon needs to be reflected, not absorbed or transmitted? Then is it that the same frequency of visible light keeps falling on something, an apple is always red in white light, why does it reflect red?

Actually, in order for us to see something, a photon has to be *absorbed*. By the retina.
