I think grain and color variation in wood is inherently beautiful. Could there be a certain pattern in a certain ebony fret board that doesn't suit my eye? Sure. Same with a Koa guitar... I am not sure who buys a 800 series priced guitar without seeing it first?
I do however cringe and get a bit miffed when people keep saying that "all black" ebony is the only good ebony. Nonsense. The wood has all the same physical properties. We were wasting, according to Bob Taylor up to 90% of the usable ebony supply, so that people could get a pure black fret board.
It is pretty clear that Taylor is trying to make a stand and change perception by putting the "smoky" (as they call it) ebony on their top selling guitars. This is a big deal to me, as I hope it is to others.
What if there was a huge supply of Braz RW suddenly discovered, but it had weird creamy lines and streaks through it? People would be jumping all over it.
If you haven't watched this....

"Let's pretend we already ran out of ebony, and years later, we found more... but it had color variation." - (paraphrased).
