I've never whined about the color, I take it all(pictures) with a large grain of salt anyway. There are actually a few places in Kansas where we do have "weeps" so I know what you're talking about. I see the distinct color changes where rover ran over the weeps. IF the pictures were taken on Earth I'd say sure, 90% probablity they're weeps. The problem is the more information we get from Mars the more appreciation I have that this place is ALIEN.
