the inner core foam on the rim is firmer on a Dbl pink rear. the yellow 2stg rear has a softer core. as for the actual racing compound of a yellow, i have heard they are whites or dbl pinks.
black exotic compund are close to purples in shore rating, black compounds are used on hi-bite carpet tracks for consistent traction and feel. in some conditions purple tend to get gripier as the race progresses.
