Gymboree, Crazy 8, and Janie and Jack have all been great for finding color-coordinated outfits for kids. I've had luck sometimes at gap kids too.
Once you find outfits for the kids, then use some colors from their outfit to find pieces in yours and DH's wardrobe to find yours. At least that is how I go about it.
