Offer a pre-selected colour-palette for colour-coding nodes and flows
A user might have a hard time trying to find just the right colour, a palette picker would be very useful for just quick colour selection. There's https://flatuicolors.com from which you can copy a nice and simple palette
I see. If I can offer feedback, I'm actually quite content with the way things are looking now (although a little bit too grey, maybe) and just a bunch of buttons within the node colour menu would satisfy me in this manner.

All you said is true. The thing is we do not know yet how exactly are we going to use colors, this is a part of bigger UX discussion.
Also related, a few pre-designed colour themes that a user can either start with or simply apply to an existing sheet a would be quite nice!
Not sure if this is implemented yet as I have not tried this out, but new additional nodes could inherit the colour from it's parent node. It might be difficult to see which node is truly "parent" as there is no clear root in the tree structure, but the middle-most or the node with the highest value could act as a reference for this specific feature.
