I feel the same way about musical tone color as I do about visible colors. They should be elegant and subtle. But sadly subtlety has gone out of style.
I recently sent a new song I was working on to a friend and he commented on how closed the filter was on all the sounds I was making. I took that as the greatest of compliments!
Upon hearing most electronic music these days, I think "is the filter broken!", because it's always wide open! Not in use! I understand that people love those unfiltered, buzzing sawtooth waveforms, but what about moderation? Think of seeing a splash of bright color on a painting that is mostly muted. Think of hearing a bright sound against a backdrop of dark sounds. Variation is what's interesting!
Color and music are in an equally bad state these days. All of our old favorite movies have been remastered with their colors blown out and over saturated beyond belief... and music is no better. I could go on and on but I think I've got my point across. I'll try to lead by example.
