I honestly don't think color has much to do with the blues now. Soul has a great deal to do with it, however. Everything to do with it. That may be why Stevie Ray Vaughn sometimes doesn't quite reach me with his -- it's more about the showy licks and less about the soul of the music.

(Not that I"m dissin' Stevie Ray Vaughn. His playing is awesome, of course. Just sometimes not quite to my taste as far as the blues go...)
