well then, whatever is the case, genetics stress color of background/substrate/bare bottom, etc. then a few of my stendkers (again the pidgeon based & red marlboros) have varying degrees of peppering - one very almost full body.
the comment that they may be lower quality discus then doesn't sit well with me since I bought from very reputable dealer.
since my background is the ocean reef with a lot of dark blues all my discus in varying degrees showed darkness, even the blue diamond was a darker blue or when lights out a very light blue.
now that I have added plants, the colors are much better on all of them including my long time very dark brown discus which turns out to be more light tan with some red & blue streaks in it.
but the peppering has reduced in only 1 red pidgeon, the other still has it all over while the 2 marlboros showed no change in peppering.
they weren't peppered when I got them so I had surmised from prior feedback it was due to the dark background & barebottom tank.
