Hi Kiril,
Thank you for your reply. You attached a Silverlight Application. Strange, seeing as how this was posted under WPF :)
Any way, I copied your entire ColorButtonDefaultStyle style, pasted it in my own solution and referenced it as static resources for all my own instances of RadColorPicker.
ie.
This seems to have had no effect on the picker's appearance. Something to do with the fact that it was meant for a Silverlight component as opposed to a WPF component?
Awaiting your reply
Thanks
