Good point Technosomy. Black vinyl is sometimes recycled, but mostly not. Recycled vinyl does have a bad reputation as quite a bit of dirt, even labels, can be part of the melt and result in noise. However, whilst that used to be the case as recycling was often slipshod, done for economic reasons, that is less the case today where recycling is taken more seriously and is not just to press as cheaply as possible. These days some bands make a green point about recycled black vinyl - King Gizzard and Brian Eno, for instance. My copy of Brian Eno's "Foreverandevernomore" which boasts about the recycled vinyl is pristine and plays perfectly. Further, whilst coloured vinyl is less likely to be recycled, the dyes can be sonically troublesome, especially if several are mixed together as in the marbling, galaxy and starburst effects popular now. I love my coloured vinyls: most play fine and some are literally awesome to look at, but my ear is a bit different to my eyes. In my own collection of several thousand lps, I would say that black and clear vinyl is less likely to be noisy than coloured. So, as always, the devil is in the detail. What remains true is my statement that in audiophile circles, with which I have a 40 year acquaintance, black vinyl is regarded as king. I stand by my attempted support of Goa Constrictor; sure coloured vinyl can be pretty, but once you go black there's no going back... 😁
