Grey Clazzio covers w/ light grey interior?

Just picked up a 2015 new with the light grey interior. Though I really like the light grey, the wife is worried about stains/dirt (we have a 4 year old). I'm contemplating adding the Clazzio covers and perhaps getting the darker grey covers. Has anyone done something similar? I'm hoping the darker grey is similar in tone to the darker grey sections of the dash, but am concern about clashing with the light grey areas of the interior not covered by the seat covers (door panels, dash, etc...) Thanks,
