Colours were banned before, beacuse of non-distinguishable rubbers.
I belive ITTF would keep 1 side black rule as is, and for other side it would only be one additional rule, it should be distinguishable from black side (not really dark colours etc.).
So 1 black side would be enough and yes, I belive you can only use 1 pink sheet (or any other authorized colour).
(Btw. it is going to be submitted for approval in 2020.)
Yes, that’s more or less the gist of it.
And I think it silly that you’re still not allowed to use the very same rubber on both wings. Discernability is no excuse there.

It is an excuse. People can age one rubber and keep another new and create discernability problems as you describe them.
Not buying that argument. At least, it does not outweigh the detrimental effect of not being able to use the same rubber on both wings.
As yogi remarked, effect of dye on playing characteristics might matter. I’ve witnessed this in some rubbers. Red Sriver and black Sriver are slightly different. I could grudgingly accept that. For most it’s like that… but some rubbers, no. Chinese manufacturers even offer some sponge types with black or red topsheets only. Why wouldn’t I be allowed, reasonably, to slap these on both sides?
Really, the rules should be: you can you whatever colour rubbers you want as long as they are clearly both distinguishable from each other
Seems more like to me a Quantum X rather than MX-P

That WAS the rule. But antispin and pips players then argued that dark purple and black were distinguishable enough, so the rule was again sharpened to black and red only.
Basically don't be an asshole and try to gain an advantage from rubber colours, otherwise whatever.
You don't have to buy it, but I have seen it myself in action and of course, I trust my knowledge of this issue. It is better to have distinctly different colors on each side so that even if someone changes the playing characteristics of the surface, you can learn that surface by knowing its distinct color. If the colors are the same, there is room for shenanigans.
