Yes it is the same. You are supposed to add your own descriptive color
names as most people see colors slightly differently.

Not that I know of.

There is an algorithm in MESS based on one of John Kowalski's programs.
He may be able to supply a conversion chart.

Not by any Coco people :) If you do some research on standard color
charts as used by the paint industry, you may be able to get some
standardized names but you will have to eyeball the Coco colors to the
standard color charts.

You should be able to make your own chart as the Coco RGB color format
is very simple. One palette byte is XX XX R1 G1 B1 R0 G0 B0. Since your
24 bit color also is to be R G B, the only question will be how to scale
the intensity from 6 bits to 8 bits. You can certainly do that by eye.
