1960s colored vinyl: chemically challenged?

[Mr.Segment]

Regarding the recent g1000 rating project. Some of the 45s involved were also released on colored vinyl. Some time back on this forum a fellow forumnite mentioned that his copy of the Monacles I can't win had changed color through the years from yellow to a dullish red. Probably due to a chemical reaction with the paper sleeve, similar or the unfortunate exposure to elves.

I was wondering if any other forumnites could share some similar experiences. Is it actually possible that some of these colored variations were of such a nature that they could actually change color over time due to an unstable chemical mixture when first pressed?

I also have a strange variant of I can't win. At first I thought it was a dead cool result of perhaps the change of color pellets (or whatever the correct technical term might be). According to Wickham's price guide it was released as both yellow and burgundy vinyl (they all sound like shit, including mine) But then I noticed that my 45 actually could be the result of a reaction to an old sleeve (as mentioned by the forumnite) Especially since the yellowing at the top might be the last gasp where the sleeve perhaps was cut to easier remove the 45. What do YOU think? Anyone else with a botched colored copy?

Also, another example. Since becoming aware of the possibility of the above scenario: anyone have a clear red see-through copy of the Fantastic Deejays Fight fire..? Because mine is a bit murky. Should it look like this or was it once a clear red? The image below looks redder than in real life due to the light of the scanner.

I can't say I've ever heard of this. Your copy looks like the one I had and is mostly likely just pressed at point where they changed the colors. They didn't clean the hoppers that dumped the vinyl pellets into and there is usually a point of mixing at the beginning and end of runs. The murky product would just be tossed from big runs but I can see them including them when doing budget orders.

If Mr. Splendid says he witnessed it change colours over the years, I have no reason to doubt it.

My copy however, of the yellow vinyl/black label of "I Can't Win" looks like the day it was pressed, pure and clear.

It's a completely different mastering than the original black vinyl/black label, with different deadwax etc. The black version has a wider deadwax area, and sounds twice as clear as the coloured vinyl version, and louder as well. However, the coloured vinyl still sounds ok, until you hear the black.

My red vinyl copy of the Fantastic Dee-jays' "Fight Fire" is also murky looking but plays fine.

I believe it's a reaction with the stiff green cardboard sleeve that did . I probably should have resleeved it then I started noticing a change , but it didn't affect the sound and I had found a black vinyl copy by then .

Coloured vinyl in the 50's and 60's was a different beast to process for coloured vinyl now. Lot more cavalier in what was used to actually colour the pellets. So could compromise the sound or effect the colour over time. Like glow in the dark vinyl, unlistenable now without fail.

my only sixties coloured 45's are some psychedelic pressings (as in colours on the vinyl, not the music!) of christian songs and children's songs from the early 60's - one is from 1962!

they were ahead of their time ha ha

RCA started the color vinyl thing I believe as a way to differentiate musical genres in the 50's.
