i remember hearing plants absorb light of all colors except green, they reflect green and that is why they appear green. I did a grow in my bathroom with a green cfl so i could shower in the morning. i didnt have any reveg problems.

Look up phytochromes. (Pfr and Pr)
Pr aborbs a photon and becomes Pfr
Pfr absorbs a photon and it becomes Pr
Total amount of Pr + Pfr stays the same.
%Pfr = Pfr / (Pr+Pfr)
If you use 660nm monochromatic light, you will cause Pr to convert to Pfr, the active form of phytochrome. Darkness will slowly cause Pfr to revert back to Pr. 730nm light will instantly convert all Pfr to Pr (%Pfr = 0), the inactive form (sleep).
Think of it like color vision, but with 2 cones. It allows the plant to see a gradient of color quality which it measures as %Pfr. At 500nm, Pr and Pfr absorb about the same so the equilibrium will cause %Pfr to change to about 50%.
The max %Pfr can theoretically go is about 85%, at 660nm because Pfr also absorbs at 660nm so the equilibrium works out to be about 85% there.

Does this answer a question? If so...how about translating into layman's terms?

Color matters.
It's not just about how much light gets absorbed for food. Plants have color vision.
A green light theoretically won't wake your plant up as much as a red light, but a far-red light will straight up put it back to sleep even if you accidentally work it up.
