Clematis Vines and Spray Paint

We have two clematis vines on the side of our garage - when they are in bloom, they are beautiful,  vibrant showstoppers.

Now the flowers are spent and it's just a vine with little greenish-gold centers.

My horticulturalist sister-in-law said that you can spray paint the centers to add some interest after the blooms have gone.  If only I had a hot pink can of spray paint for those little centers. . . . and didn't have siding behind the vines.
