(resending to the list, as i answered to jean-yves privatley only by mistake - sorry)
thanks jean-yves,
thats some serious wizzardry and it seems that i could build my oscilliscope from that :-) have to study it a bit more to really understand, whats going on under the hood.
in the meantime i built sth with purr data, which has a properties dialogue with a colorpicker. for arrays. (i wanted sth simple + workable quickly). ultimately i think, that would be good to have in pd as well.
also will check out your mob collection, as i am a big fan of mobmuplat, which sadly seems dormant but still keeps working on the newest iOS.
best hans

Hi hans,
You should try my sarray abstraction (based on this discussion https://forum.pdpatchrepo.info/topic/11184/colarray-a-graphical-array-where-...)
download here https://github.com/jyg/mob/releases/tag/mob-0.1
There is some trickery to get an array name with $0 tag, but it's explained

Re: [PD] is there a way to color the points/curve in an array? From: "hans w. koch" hansw.koch@gmail.com Date: 28/05/2021 à 22:02 To: Pd-List pd-list@lists.iem.at
thank you, roman and alexandre, for the pointers!
it seems, the best option is to wait, till the discussion alexandre referenced (https://github.com/pure-data/pure-data/pull/711) comes to fruition. purr data has implemented such a color picker for arrays, so that would be the second best option. i looked into Jmmmp multiarray, but i seemed to be better suited at displaying static waveforms. maybe i overlooked something.
i am (ab)using pd as an eight channel oszilloscope. things get messy pretty fast without colors.

using 4 superimposed arrays to show different waveforms (e.g. phase differences), i was wondering, if there is a way to assign a unique color to each array, to visually better separate the waveforms. i found a discussion "[PD] Array Enhancements" about that (and other things, like "Hide Array name” - still not working) from 2009 [1] and another one "[PD] colored arrays?” from 2007 [2], but no tangible result - or i missed that, then sorry!
As someone mentioned in one of the other threads, you could achieve colored array displays with data structures.
An example is here: https://www.netpd.org/fl-hishv.png
Probably much closer to what you actually need is the [multiarray] from the jmmmp library. It's in Deken.
