I made many themes over the years, Unity pro, Softimage, now recently I had a working theme on my computer based on the OP-1 synth, but it wasn’t the best for 3d content creation.
Anyways so I started with the Default theme in Blender, and just made what I consider improvements on it.
Tweaked the over saturated accent colors, and came up with a more brighter and less contrast-y blue and orange I started using all over the place. Also introduced a green for the check-boxes.
One thing I can’t stand is the dark, transparent menues or tool/props-panels. So got that opaque and in the gray tone as the rest of the UI.
I call it Default++ and here are some screenshots.

Some tweaks on the curves, selected and handles.
I will go through nodes today, and probably get a link up for the theme file.
