Changing the colour of a TreeViewNode's focus rectangle

Hi,

I have a treeview with HideSelection = false - so whenever I select a node I get a visual indication by way of a grey rectangle around the node.

Is it possible to change the colour of the rectangle without having to do all of the node's drawing myself (on other words I don't want to write code in OnDrawNode to achieve this)?

Thanks very much,
