* This class represents a color expressed in the indexed XTerm 256 color extension, where each color is defined in a

|
* lookup-table. All in all, there are 256 codes, but in order to know which one to know you either need to have the
|
|
* table at hand, or you can use the two static helper methods which can help you convert from three 8-bit
|
|
* RGB values to the closest approximate indexed color number. If you are interested, the 256 index values are
|
|
* actually divided like this:<br>
|
|
* 0 .. 15 - System colors, same as ANSI, but the actual rendered color depends on the terminal emulators color scheme<br>
|
|
* 16 .. 231 - Forms a 6x6x6 RGB color cube<br>
|
|
* 232 .. 255 - A gray scale ramp (without black and white endpoints)<br>
|
|
* <p>
|
|
* Support for indexed colors is somewhat widely adopted, not as much as the ANSI colors (TextColor.ANSI) but more
|
|
* than the RGB (TextColor.RGB).
