White colour for the dish helps keep the dish cool and thus reduces the tendency of dishes to deform in the heat. This is particularly relevent to plastic dishes.
It is important that the paint is matt and non-reflective, otherwise the reflected heat can easily melt or burn the feed window and overheat the LNB assembly.
If you are contemplating a 2.4m or 3m dish, note that surface accuracy is a serious issue. If the dish is made up of several panels, make sure the panels line up perfectly and that the dish rim is flat to <2mm.
Best regards, Eric.
