AvP 2 definitely made use of a wider range of color than the first.
For me, AvP = better MP (although the SP for it's time was more than competent; I still fondly remember getting my hands on the Alien version of the demo, you start off in a leaky, poorly lit room with a semi-reflective puddle to show off the the neato dynamic water effects which just made my jaw drop) , AvP2 = better SP.
