* Intends to provide support for the very evil index to triplet issue and
* will likely replace the color constants interface for HSSF 2.0.
* This class contains static inner class members for representing colors.
* Each color has an index (for the standard palette in Excel (tm) ),
* native (RGB) triplet and string triplet. The string triplet is as the
* color would be represented by Gnumeric. Having (string) this here is a bit of a
* collusion of function between HSSF and the HSSFSerializer but I think its
* a reasonable one in this case.
