Is there any difference in terms of sound quality between different vinyl colours?
There are numbers of limited and special editions of vinyl LPs nowadays, and a lot of them differ from standard edition by vinyl colour: transparent, white, red, splattered… Is there any difference in terms of sound quality between a black 180g vinyl and a coloured vinyl?
I have read somewhere that white vinyl has the best quality between all the coloured ones, but not as the black one.
Is that true? And based on what parameters?
Wouldn't it be the *material* that could affect the sound, and not the color of light it reflects?
Yes, I agree. So (probably I didn't ask a clear question...) are there any differencies in material used in different colour vinyl that affect audio quality?
If two materials reflect colour differently, isn't it because one has a different chemical composition? So they would be different materials.
@topomorto A hundred thousand different materials can be the same color. They're not going to all be moldable the same way, resist wear the same way, etc.
@MatthewRead Isn't the fact that different materials have different properties the whole point of the question? What if different colour pigments affect the grain size of the vinyl substrate, for example?
@topomorto Again, two things of the same color can have wildly varying properties. There are many similarly-colored pigments that will have other different effects. The gist of my comment is that the question should be asking about materials, not colors, so as to better get at the "point" you describe.
@MatthewRead honestly, I'm sure most of this site's readers are aware that if a thing is a *different colour* it's *because it's made of different stuff*, so it's already fairly clearly a question about materials. Mentioning the colours (the thing that catches people's interest in the first place) is just a bit more human!
@MatthewRead and it's true that things of a similar colour can have different properties. But we're not talking about *all things*, but *records, as manufactured in the real world in which we live*. And it seems reasonable to assume that the range of ways in which *records* are commonly made and coloured might be small enough that an answer could be given to the question as phrased, if someone comes along with knowledge about the manufacturing processes used. If that person is you, then by all means answer, even if it means that you have to challenge some of the assumptions in the question!
If you're asking about the difference between "180gr vinyl and a [regular weight] coloured vinyl", then 180g usually has better sound quality when compared with the regular 120-140g vinyls.
If you're comparing black and coloured vinyls, there is a small noticeable difference in sound quality.
Let's look at the production of coloured vinyl
[in order to create vinyl records] little vinyl pellets are poured into a hopper, or chute, which feeds them into an extruder. The extruder melts the vinyl down into thick hockey puck-esque patties often called cakes or biscuits. Typically those pellets are black, but different chemical compounds can produce unique colors (like Pepto Bismol pink) or even transparent vinyl. Solid colors or pellet mixes can be tossed into a hopper and extruded into biscuits just like black vinyl.
Sounds good so far. However:
Despite its collectibility and cool factor, coloring vinyl involves a minor trade-off in sound quality that vinyl newcomers may not know about. The chemical properties of pigmented vinyl just don't sound quite as good as "virgin" black. Blackwell estimates the sound quality is somewhere between 90 and 95 percent of that of a black record--a small enough variation for the average listener to never notice, but enough to turn off serious audiophiles (who are probably the only ones with expensive enough sound systems to hear the difference). The Carl Sagan "Cosmos" pressing, for example, sounded noisier whenever a record player's needle hit a glow in the dark spot.
As you can see it's a tiny trade-off, but it might be noticeable by audiophiles. However properly mastered and pressed coloured vinyls are often better than average pressed black vinyl records.
Following the link you provided I found a very interesting article. That was what I was looking for!
Anecdotal evidence (my own) shows that coloured vinyl (popular in the 70's punk era) and more so, picture discs had an inferior sound quality. They were also much more prone to warping for some reason. I'm not an "audiophile by any means, an nor were my friends, but we could hear the differences. Coloured vinyl was bought as a novelty or to "complete a set" (we would by all 7" and 12" pressings of certain songs or bands) and normally not get played, preferring the regular black discs to listen to.
