I have a question about why the color of an object is as it is. This is about episode 5 in the tv-series Cosmos from 2014.

From what I understand a blue object abosrbs all the colors except blue?

Also from what I understand when an atom absorbs electromagnetic waves (or a photon) with a certain wavelength the electron moves to a higher energy level. But after a while the electron moves back to the lower energy level and when that happens a photon that corresponds to that energy level is released?

So why do we for example on a blue object see only the color that is reflected? Shouldn't we also see the absorbed colors that are released when the electron moves back to the lower energy level?
