Taken from the Wikipedia page, I've created a resident file containing around 1,297 named colours, from COLOUR_ABSOLUTE_ZERO to COLOUR_ZOMP.
The source code is here http://blurg.org/spiderbasic/sourcecode/colours.sb and the resident file is here http://blurg.org/spiderbasic/residents/colours.res
I would have preferred these as constants, but RGB cant be used with constants...
