Hi Foxxer,
The style changes the behaviour of the titlebar items and not the colors specifically; instead the color comes from the active skin. If your users pick a skin that has orange for buttons then you'll get an orange button in the titlebar. For most AC controls there is a SkinData.SkinManager property that you can use to set a skin for a specific control but the title bar items don't have this property so I don't think you'll be able to override the behaviour without some code. I don't have any code handy to do that but it will be something like implementing the OnCustomDraw method to draw the panel – I think there may be something on this in the demo-apps link off the AC main page.
Something else to consider though – you might like orange in the title but the point of giving people skins is that *they* might not like orange – if they pick a purple skin they'll probably expect a purple button and if you force it to be orange it will look bad. Just something to consider.
EDIT: I just looked into the titlebar items and can't see any drawing methods you could intercept. I don't have time to look into that further so hopefully Serge or someone else from the forums jumps in soon to offer some advice. Best of luck.
Regards,
Hamilton
