Deborah,
You may already know this in deciding on color preferences, but since not everyone’s aware of it, I want to just mention that there’s a tradeoff to consider between aesthetics and durability.
The darker shades of canvas contain more UV-resistant additives and thus last longer in the sun.
(Some people also claim they hide dirt better, but personally I’ve never had any luck in color-coordinating my canvas with local dirt sources.)
