From Paiste:I would think the sound would change as the paint wears off. I mean, it's a coating, it has to have an effect on sound.
"Color Sound 900 cymbals are based on the range of models in the concurrently launched 900 Series. While they feature essentially corresponding sound and function, the color coating causes a slightly drier sound, shortens the sustain a bit, and results in a more focused attack. Significantly, the same flexibility and giving feel as in the 900 Series is present.
Extensive research and design efforts have resulted in the most stunningly beautiful finishes: luminous translucent colors preserve the natural appearance of grooves and hammer marks and present a vibrantly radiant appearance. Notably, decades of experience have proven the Color Sound finish to be exceedingly tough and durable - the finish will not ever crack, chip or peel."
I didnt see anything about what the color is or how it is applied.
