It made me think of candy-colored filled liquorice for some reason. It's a personal recreation of a theme on the first screenshot example from the UI proposal doc: LINK
The main flat grey coloring and Blue selections were based on the screens. Mesh editing, UV editing, Clip, Sequence, Scripting and Console insides are based on my own preferences.
Feel free to modify to make your own theme ideas.
<ul><li>A whole bunch of fine-tuning to make all the colors more consistent. Changed the UV colorings again, this time to match exactly to mesh editing. </li>
<ul><li>Updated UV section coloring to match closer to the rest of the theme</li>
<li>Updated 3D view coloring; Face Area/Angle text, Edge Length/Angle text, Auto/Vector handle selected color</li>
<ul><li>Set font size to Default Factory settings size.</li>
<ul><li>Updated node coloring</li>
