Shrubs with some color for a Mid-Atlantic home?

Hi! I live in Maryland and have had this house for 10 years. All of the plants and shrubs in the front of the house were installed by the contractor and are pretty bad. We have these thorny shrubs that we have kept because they add some color to a gray stone house. I would like to get rid of them and am looking for some suggestions on som bushes or shrubs that will add some color, but won’t leave scars when I try to trim them. Any suggestions? Thanks!
