	var name   = 'color';

	return function (css) {
		css.walkDecls(prefix + name, function (decl) {

			var value = postcss.list.space(decl.value);

			if (value[0] === '*') decl.remove();
			else decl.value = value[0];

			if (value[1] && value[1] !== '*') decl.cloneAfter({ prop: 'background-color', value: value.slice(1).join(' ') });
