Thanks for the response. I want to change the color for a zone. I have requirement like There will be button and text box area in a region, the background color should be changeable. For this I have put one zone, on top of zone I have put 2 web parts, one for button and one for editable text. This is inside my page template. For different web sites I can put different color for this zone. So I want a color picker in design view, where Designer can choose from to put the color for this zone.
I can achieve this through web part container, where I will put css class, and specify the color. But I dont want to do like this. Can I have a color picker to do this work, instead of manually doing the changes in css?
