obviously camo pattern is less important then we as hunters believe it to be, however to answer the specific question it really depends on your normal set up. Are you on ridge tops more often where you are skylined or are you in bottoms with hillside back grounds?
I run a lot of solids as far as pants go but Ive also found over the years I really stay away from dark type camo (most of realtree and a lot of mossy oak). My personal favorite that seems to work great no matter the season is First Lite Fusion, however if I am skylined on most of my set ups then lighter colors like Elevated2 work really well.
