Compare PQD Surf Blue Pearl to PBC Viper Bright Blue Pearl in this brochure:
http://www.sherwin-automotive.com/sh..._ColorBook.pdf
They are similar, but if anything PQD is lighter.

Then look at this Dodge dealer brochure:

Surf Blue Pearl is listed as Surf Blue Pearl / B-5 Blue (so confirmation these are now one and the same color). However, that color does not look like Surf Blue Pearl anymore. Instead, it is a few shades darker than the PBC Viper Blue Metallic. It also appears to be a closer match to the color shown in the Dodge Challenger brochure we all have or have seen. If this is the Challenger Classic color I am happy!
