Mineral type.
A rock’s color is primarily set by the minerals it contains (and any impurities in those minerals or surface staining such as iron oxides). Texture, grain pattern, and grain shape can change the rock’s appearance (how the color is distributed, how light is reflected, or whether colors form bands), but they don’t determine the fundamental color the way mineral composition does.
