Yeah, agree. Assuming those photos are color correct (which they probably aren't), they don't quite match up. I thought I read Zu uses automotive paints, and Fender used their own versions of the automotive paints in the late '50s and early '60s guitars. I think there were about 5 different colors copped from the Fords and Chevys of the day.
Ahh, that's it! I have a guitar in Daphne Blue, and the other color is Sonic blue.

I really love these colors. I'm not sure they'd work on speakers for me - but I appreciate that these speakers can pull them off!
