*virgin* vinyl is translucent. mfsl and quiex lp's were pressed on virgin vinyl. hold a mfsl lp up to a strong light source. you can see through it. now try the same with a "typical" pressing. you can't see through it 'cause it's made of inferior, not virgin, vinyl. this has nothing to do with "coloring." in fact, most colored records (not opaqely colored) are pressed on virgin vinyl. -cfb
