Incredibly this post is in English ;).
I've decided to publish the colour theme I made for Cinema 4D R10. I didn't like the default one because the colours were too dark for my taste and the overall scheme lacked good contrast between the elements (check boxes, buttons, little switches, etc). For this theme I've changed some buttons to fit with my colours. As you noticed, I am fond of the Windows's colours, so I want my applications to have a consistency in the interface. Most importantly, perhaps, it's that I changed the little tiny dots in the Object Manager. I've made the different states on/off/default very clear and easy to remember.
Hope you like it.
If you like the screen shot, you may download the file. Just extract the files in your \%Cinema 4D installation folder%\resource\schemes\ and run C4D R10 :). Select the colour theme from the Preferences dialog.
P.S. Don't worry about the French user interface.
