Paint recolours placed blocks, walls and furniture — apply it with a Paintbrush, Paint Roller or Paint Scraper, all bought from the Painter. Beyond the basic colours there are Deep and Bright shades plus special Illuminant, Shadow and Negative paints.
Buy paint from the Painter, load it with a Paintbrush (for blocks) or Paint Roller (for walls), and click to recolour. The Paint Scraper removes it. Paint changes only the colour, not the block itself.
Beyond the standard colours, Illuminant Paint glows in the dark, Shadow Paint darkens to near-black, and Negative Paint inverts colours. Deep and Bright variants shift each colour's shade.
