Colour maps
Grass, leaves and other foliage are drawn with grey textures tinted by a colour taken from a colour map, a 256 by 256
picture under textures/colormap/. Observed · the leaf textures and colour maps of bedrock-samples v1.26.60.5 The
vanilla resource pack has eight: grass, foliage, dry_foliage, birch, evergreen, swamp_grass,
swamp_foliage and mangrove_swamp_foliage. Proven · every file of textures/colormap in the v1.26.60.5 resource pack
Sampling by climate
Section titled “Sampling by climate”A map is read at the biome’s temperature and downfall, as the temperature–rainfall triangle of Java Edition’s grass
and foliage maps: the grass and foliage maps’ pixels change across the picture, the rest are flat. Inferred
grass has 4,663 distinct colours and foliage 8,837; dry_foliage 268. Proven · every pixel of the three maps in the v1.26.60.5 resource pack
The single-colour maps
Section titled “The single-colour maps”Four maps are a single colour on every pixel, and swamp_grass has two:

No data file names birch or evergreen: the engine applies them to the leaves of those names. Inferred The
birch and evergreen colours are the constants Java Edition tints birch and spruce leaves with, and the swamp
foliage colours its swamp and mangrove swamp foliage colours; swamp_grass’s two are the two colours Java Edition’s
swamp grass alternates between by noise. Observed · Java Edition 26.3’s block colours and biome definitions
Being flat, these maps give the same colour in every biome; a pack that redraws one can make it vary by climate. Inferred
Client biomes that name a map
Section titled “Client biomes that name a map”A client biome’s minecraft:grass_appearance or minecraft:foliage_appearance may give its color as a map,
{"color_map": "swamp_foliage"}, instead of a colour. Observed · the client biomes of bedrock-samples v1.26.60.5 Three
of the 89 vanilla client biomes do: swampland and swampland_mutated (foliage swamp_foliage) and mangrove_swamp
(foliage mangrove_swamp_foliage), all three with grass swamp_grass. Proven · every client biome file of the v1.26.60.5 resource pack
A biome that names no map takes its grass and foliage from grass and foliage. Inferred
A resource pack that replaces a map’s file changes every biome and block drawn with it. Observed · the La Nature resource pack, whose plain white birch, foliage and swamp maps leave its own coloured leaf textures untinted
A pack’s client biome file of the same identifier replaces the vanilla one, so a pack biome without
foliage_appearance no longer names the vanilla map. Inferred
The vanilla data cannot show it, and no pack observed overrides one of the three biomes that name a map.
