'Color' is just the square shade you can see on a checkered board, light or dark. The term 'meta-color' usually refers to another (hypothetical, i.e. not actually visible) coloring scheme using more than two colors in some other pattern, each meta-color indicating a set of reachable squares. E.g. a Dababba can only reach a quarter of all board squares, so that you can put four Dababbas on a board that could ever collide with each other, each on its own meta-color.
