When you change the colour of a binary mask image through the context menu in the Data Manager, it changes only the "color" property but not the "binaryimage.selectedcolor".

This is very confusing, as the same mask is rendered with different colour if it is selected and when it is not. I understand the concept of the two different properties, but in my opinion the context menu should change both. You can still change the properties independently through the API or the Properties View.

On the top of that, the render windows are not refreshed after you change the colour. You need to resize the window or force a refresh in some way to see the colour change.

Fix will follow.
