/** @defgroup GUI_SWIM_COLORS SWIM color definitions
 * @ingroup GUI_SWIM
 * The Simple Windows Interface manager (SWIM) supports 8-bit RGB332,
 * 12-bit RGB 444 (in a 16-bit field), 15-bit RGB555, 16-bit RGB565,
 * and 24-bit RGB888 (in a 32-bit field) color.
 *
 * SWIM is configured for the color type at build-time based on the
 * the COLORS_DEF definitions. Select one of the following values to
 * configure SWIM.
 *  8-bit RGB332 : COLORS_DEF = 8
 *  12-bit RGB444: COLORS_DEF = 12
 *  15-bit RGB555: COLORS_DEF = 15
 *  16-bit RGB565: COLORS_DEF = 16
 *  24-bit RGB888: COLORS_DEF = 24
