I believe the Summit paint it is a little darker since it matched the latest grabber blue. I got some touchup paint from Ford for our B3 challenger and it was darker. It was painted on the exterior with PPG paint and it matched the door jams perfectly, but the touchup was a little darker. My B3 Duster was painted with Sherwin Williams basecoat/clearcoat and they still list the B3 paint code. If you are not trying to match/blend existing paint, it may be close enough to your satisfaction.
