Colors

For dyes, the color groups used in Minetest Game have been widely accepted. If you add a dye, you should add the appropriate groups. The groups have names like basecolor_white, excolor_sky_blue and unicolor_dark_green.

See game_api.txt, section “Dyes” for a detailed description and see the dye mod for an example implementation.

Otherwise, intended for living things like animals and the player. This could imply some blood effects when hitting.
