I've done two different palettes based on the two families we have: DeepSea (based on Cool-Grey) and another called Neutral. In my current branch for this I created a theme switcher to be able to view and test them. Personal opinion: Neutral is better and works better with the current yellow. It takes about a moment for the eyes adjust to the new color and then...they relax in the the perfect color symmetry.
DeepSea is more "blue" matching our bluish elements, Neutral is warmer. Part of our issue is over time our UI has been using both warm and cool valued grey values (Not ideal).

@hundreds-twilight-32833 I tried to address the color contrast and spent time to make it less dark than proton.
