Sorry, I don't understand your question. You appear to have listed out all
the (colour_name, colour_index) pairs in the colour_map used by
xlwt.easyxf (for fore_colour and every_other_colour). There are 56 of
them. However some names map to the same index.
If you haven't already done so, please read the section entitled "The
Palette; Colour Indexes" in the xlrd docs
(https://secure.simplistix.co.uk/svn/xlrd/trunk/xlrd/doc/xlrd.html)
256 ** 3 (16.7 million) different colours are possible, but an XLS file
limits you to one palette of 64 colours. Of those, 8 are fixed, leaving 56
variable.
Currently, xlwt has no API to specify a non-default palette.
If the above remarks don't cover what you are interested in, please feel
free to ask again ... saying what you are trying to do might help.
Cheers,
John
