hi,
when i am sending a couple of notifications, to my android (samsung) phone, with an color assigned, the single notifications will have correct colors.
but android is grouping the notifications (by app), if too much notifications on the lockscreen or pulldown-menue are listed…
unfortunalety, the group gets the color of the “first” notification for an app…
examples from my phone:
example1:
collapsed
unfold
example2:
collapsed
unfold
background: im using notification channels as well, to get different sounds and vibrationspattern as well (what works fine), but i want to have alarm notifications beeing standing out visually, but with that grouping it is bashed, when some old notifications are in list 
could this color behaviour for grouping be configured?
btw: if i do not use any specific color setting, a default color is used (some like cyan color). 
where i could modify the default icon color behaviour?
