49 * MATCH_NORM_COLOR means that the color that is set to this value
50 * will actually use the corresponding fg or bg color from the
51 * so called Normal Color. A MATCH_NONE_COLOR means that the
52 * corresponding fg or bg color will just be left alone, so that
53 * it will stay the same as it was. This is useful when you want
54 * to change the foreground color but let the background match
55 * whatever it was before, for example in colored index lines.
57 * Note: these need to be RGBLEN in length because they are sometimes
58 * used in places where an RGB value is expected.
