Hello Telerik Team,

I want to change the color of yellow when hovering using mouse over in Radpanel bar or RadpanelItem.

Changing color is not easy with most of the skins because they use images to accomplish their styling. See the different skins here http://demos.telerik.com/aspnet-ajax/panelbar/examples/functionality/firstlook/defaultcs.aspx (Click the Skins drop down in the upper right). I believe the Simple skin is the only one that you can style with css. Otherwise you can this tool: http://stylebuilder.telerik.com/ to edit skins.
