Board and batten siding can be vinyl, wood or cement board. If the latter two, it would be painted.

James Hardie manufactures a cement composite siding - they offer the Board & Batten profile. Even better, they use ColorPlus Technology, baking the paint onto the board in the factory. There is a 15 year warranty on the color (which will not fade overtime) and a 30 year warranty on the board itself. Here's an example of a recent install our team completed. This color is Iron Gray.
