I may be alone in the camp, but I consider the change of the turntable colours to be a decline; and it's long been the visual marker for me of the point where Price began its gradual descent from its aesthetic peak.
The many crisp, clear quality videos Pluto TV has uploaded to their YouTube channel has allowed me (without access to the channel itself) to garner a good taste of the flavour of Price in early '80s. The change in the turntable colours to the purple, orange and red always stuck out to me as something off, and now I finally understand why that is: It doesn't match the rest of the set.
It may be all the same colours in the new design (albeit, with some slight differences in shading and red being much more prominent), but the layout of the colours no longer follows the pattern similar of the doors. The doors have their different coloured strips of varying thickness around the edges with the prominent white section filling the middle. The turntable followed this same design pattern: a purple border, a narrower strip of red inside as a border and then the orange fill. The shades also matched with the door colours, and the green frame in particular matched the same shade of green used on the doors. The shade of green appears changed in the new design, and it no longer matches. The lights around the turntable also complimented the doors as well for a parity in design, which was lost in the revamp.
On a similar note, the '83 music package, while acceptable in its own right for being production music of good quality (instead of, say, the '94 or '03 music packages), doesn't match the '72, '74 and '76 packages otherwise in use at that point, which complimented each other very well in terms of similar arrangements and styles. The '83 package is distinct as its own flavour. It's a good flavour, but it doesn't match the rest of the flavours.
I could add the Barker wall as well. The original matched the doors. The new one didn't.
