From my experience, this discussion is getting quite special attention in this list with 35 messages so far (and counting). I counted a dozen people engaged. This is about as good as it gets... Moreover, I did a facebook poll which now amounts to 33 votes. You sent 13 emails already and people are still responding to you. Some people probably just decided not to get into this and are aware. Between the list and facebook, that's at least 50 people. Don't worry, this is on!
I counted only 2 people strongly opposing to colors, yours and bbob's but you're the one really going for it :) Not that I wanna say you shouldn't. Where I'm getting at is that it seems you're not succeeding in resonating your voice. The bottom line is: I think this discussion *is* going and happening, but maybe not the way you'd hope...
cheers
