| 100 | * RGB values to the closest approximate indexed color number. If you are interested, the 256 index values are |
| 101 | * actually divided like this:<br> |
| 102 | * 0 .. 15 - System colors, same as ANSI, but the actual rendered color depends on the terminal emulators color scheme<br> |
| 103 | * 16 .. 231 - Forms a 6x6x6 RGB color cube<br> |
| 104 | * 232 .. 255 - A gray scale ramp (without black and white endpoints)<br> |
| 105 | * <p> |
| 106 | * Support for indexed colors is somewhat widely adopted, not as much as the ANSI colors (TextColor.ANSI) but more |
| 107 | * than the RGB (TextColor.RGB). |
