Arteryx looks to have some really nice options too, I think they sell some grey stuff. Mountain hardwear has some good options too but I think they are pretty heavy into black pants. I also own the green Marmot scree pants I picked up on sale at REI for like $50, love them except for the drawstring cord in the ankles...I'll probably cut it out as I have no use for it and when I try to wear them around town with sandals I get tired of stepping on that stupid shock cord. Another pair of pants I love are the Prana Zion stretch pants. Not so sure how they would hold up on the mountaink, they are a little thin. But super comfortable and great fit, I also like the design of their cargo pocket and the adjustable waist is nice since you don't need a belt. It must hold up well enough, I ran into a dall sheep guide who was wearing a pair...granted the season hadn't opened yet, not sure how well they held up.
