How come clothes that are gray seem like they don't need to be ironed?

Question:I'm not complaining or anything but why is it that sometimes when gray clothes come out the washer and dryer they don't seem nearly as wrinkled as other clothes. Just curious. Has anyone else noticed this?

Answers:
Most of the time, gray is a blend of actual fibers, not dye. A heather gray t-shirt may even actually have a small bit of polyester in it, and poly doesn't generally wrinkle. Hope that helps!
