Other Block Colors
Certain block types have special coloring methods not covered by Custom Biome Palettes.
A 16x1 bitmap used for redstone wiring and particle effects only. Other redstone colors (torches, repeaters, etc.) are pulled from the block textures as normal. The x-axis of the redstonecolor.png bitmap represents the current strength. 0 is fully off, 15 is fully on.
Pumpkin and melon stems
An 8x1 bitmap used for stems at each growth stage. 0 is a sprout, 7 is fully grown.
