[78-L] questions about blue shellac

[neechevoneeznayou at gmail.com]

How is shellac made blue? A dye of some kind I presume...same as making 
it black.

Why blue? A response to Victor and its obsession about red seals and 
such? Inspired by Blue Amberol cylinders?

Who besides Columbia made blue shellac records?

And most important, does it sound different? (I think not). Anyone claim 
they can hear a difference between blue and black shellac (or any other 
color?) Anyone done a double blind test?

Any other colors for shellac besides black, blue, splash and clay?
