It's been a while, and then post surgery my brain has recently been rendered somewhat dumb.
Anyway, colours in Vanilla, always good for some fun.
Work in Progress.

It does quite a lot when you switch to edit mode, and the colours stick when you switch back.
Anything added to the patch (or edited) has the standard colours.... but switch out of edit mode and back in and the new colours are there.
I am wondering if that could be useful.......?
So a few new ideas could come out of this..........
Certainly Windows Vanilla 0.49......... vanilla_colours-plugin.tcl
Put it in a Pd known path, and delete it or move it elsewhere to stop the magic.
Please let me know if it works on other systems.
Edit the file to change colours or if you don't like arrows in edit mode.... it's fairly obvious.
Available colours........ tcl colours.txt
Some things not working.
Some weird stuff.
When it is finished I will make a menu item for the console so that colours can be chosen..... maybe.....

@whale-av Hi, I've just tried it by placing the plugin in my externals folder on Win 10 Pd 0,49. When I first open a patch it looks a little disconcerting until I enter edit mode.
Looks really useful though.

@Balwyn Might solve that......... vanilla_colours-plugin.tcl
Might not.
It's a shame if it has to be tailored to different systems, but that did seem likely.
You are free to play with the contents and see what you can achieve.
