I have a burgundy pair and an older denim pair and I concur with Diana -- they have a different hand and feel. I like them both, actually, and don't find the coloured ones too stretchy even though they definitely have a bit more stretch and they are lighter weight. I have the same size in coloured and denim, too -- my regular denim size -- but the denim ones currently fit me more snugly due to weight gain, whereas I don't notice that in the coloured version, which I guess has a bit more ease due to the stretch.
I love this cut of jean beyond reason. I wish I'd got the olive but the people at the Ottawa Nordstrom told me they were not available in the Canadian system. By the time I learned you'd got a pair the sale was over...
