Hello all,
I am currently making a Sonar theme that I call Iceberg. I found a nice iceberg picture, extracted the colors to make my own custom color palette and used this palette in the theme.
I've changed about 80% of the items in the theme editor (didn't change anything related to ProChannel), so almost everything is customized, not only the track panel or the console. Unfortunately, due to lacks in the theme editor, there are some things I cannot change (or don't know how to change).
Here's what it looks like:

(right-click and open it in a new window or tab to enlarge it to its full size)
Let me know what you think.
I'm using it most of the time and find it rather smooth to the eye.
And here's the photograph on which the colors are based:
Please note that I'm using the French version of Sonar, that's why some texts are in French :-)
