Hello ladies and gentlemen.
I extracted Qt5 Color Scheme from Maya 2017 U2 which has all 63 colors
So you can use its color palette with the default Fusion theme on your Qt Applications.
Now you can present applications which has a clear, robust dark color theme of Autodesk Maya.
Example
The code somehow gives an error on the forum, you can check it on my personal blog.
