Clear vinyl vs. regular black vinyl

I just got my second clear vinyl record yesterday, the Stones Hot Rocks on 180g, not from any special manufacturer like MFSL or Analogue Productions and the like. The first one was Donald Fagen Sunken Condos. These albums sound particularly good for not being pressed by a "special" audiophile label.

Is this just a coincidence or is it better, and if so, why aren't more records produced this way? I heard that eliminating the dye in the vinyl could improve the sound, but I was wondering if there is a consensus out there. 

I'm not talking about other dye colors or ones with pictures on them, just plain clear vinyl.

Thanks.
