I suspect that there is a "cultural" bias that makes the idea unworkable. I haven't found a definitive source, but I think there are a lot more hues and shades of red that have names than hues and shades of blue, for example. If I were doing this, I'd just prepare a table with 32 color slots or so [*1*], start at a random spot (say 017:00005f) of https://en.wikipedia.org/wiki/File:Xterm_256color_chart.svg, and pick spots by jumping southeast like a chess knight (i.e. 017->030->043->086->...) until the table is filled, wrapping around at the edge of that color chart as necessary. [Footnote] *1* ...because I do not think the thin graph lines painted in too many colours on the screen would be easily distinguishable from each other anyway.
