generally, if it has a diamondplate logo, it's hot pink.

the protos have DP logo and aren't hot pink, but the regular production games with DP logos are all hot pink.

PFR here in the states was making the most awesome custom CFTBL playfields, they would take the regular pink ones, then airbrush the pink 'hotter' pink than the hot pink ones, along with doing neon greens, yellows, etc too.
