You raise a very important point here.
But I guess the small TT market issues cannot be the fault of the manufacture.
The issue we have is, there needs to be 10 folds more players, maybe 20 to 30 folds.
with bigger numbers, the cost could come down - then we can have more colours.
I understand about logistics of manufacturing, distribution, stocking.
That would be a valid point — if you assume manufacturers start to produce ranges of colours for the same rubber. Blue Mark V, green Mark V, orange Mark V, brown Mark V, red Mark V, that.
I don't think that's viable either. Yet I do think it would make sense for (say) Friendship to reintroduce the classic 729. It might make sense for Joola to reintroduce that undyed (golden brownish) rubber.
(And I still want to use two identical black rubbers and be done with it, personally. And can't, because of foolish restrictions.)
Vendors have options. We might end up with all Rasanter R variants in black or green, and the V variants in black or blue. Or we might end up with R39 in pink, R42 and V42 in blue, R47 and V47 in red, and R50 in green. (I left out red intentionally; realistically, the 47's in red would be the conservative marketing approach when seeking distinctiveness through colouring.)
There's no saying, upfront, how manufacturers will use colour to shape and position their product lines. I wouldn't jump to the conclusion that from now on all vendors will produce all rubbers in all colours, resulting in that logistics nightmare you fear. I don't think the vendors are all that stupid, and they have some awareness in the issues of scale of production and distribution.
Mark V is probably a bad example, let's consider it. It's a classic, and I would guess it remains available in black and red. Messing with classics is a bad marketing ploy, and I don't see much incentive for Yasaka to spoil this traditional favourite's reputation by going all out in crazy, flashy colours.
I do see Yasaka create a new rubber with its own distinctive color, as one more way to make it stand out. So we might just get a bright yellow (and black) Waking Dragon at some point — and no red. Manufacturers have this choice.
In the end, to me it's lifting a restriction. Yes, that can lead to insane derailments. But the incentives, to me, don't seem to lead that way.
(What I would like is to simplify and be done with all this. All rubbers should be black, period!
)
