Painter

The Painter is an NPC who sells Paint and painting Tools, as well as Paintings and Wallpaper. He will arrive after at least 3 other Town NPCs have been acquired, and a suitable House is available.

The paintings that the Painter has for sale change based on the biome he is living in, and based on the Moon phase. During the Christmas season, the Painter sells a variety of holiday-themed wallpaper.

In actuality, the Painter requires 4 other NPCs to be present in order to spawn, however the Old Man is counted as one of these. Since the Old Man is present on world generation, only 3 other Town NPCs are required initially. Once Skeletron is defeated, the Old Man despawns permanently, and the Painter will not arrive until 4 Town NPCs are first present.

Wallpaper

 * Note: Only Christmas-themed Wallpaper is available on the console version.
