Hi Kenneth Jackson,
Thank you for the feedback.
I understand your concerns. However, currently we do not have any specific time-frame for the Aqua, Desert and Breeze theme designs for RadRibbonBar. Of course, your vote raises up their priority in our features list.
Until the required themes are ready, you can use our Theme Alpha Blending feature
to make a theme based on an existing theme. You can save the theme as an xml file and then edit it with Visual Style Builder. I am attaching a sample project which demonstrates how you can modify the RadRibbonBar ControlDefault theme in order to get a 'beige' color scheme.
If you have additional questions, feel free to contact me.
