Are you sure? This just gives: undefined function rgb.

I even resorted to scanning through the source, but AFAICT the colour
for a data series is defined only once, when the plot command is parsed,
but before the data file is read. 

e.g. I have the data below, where the columns are r,g,b,frequency, and
colorname

I would like to plot "rgb space" such that preferably each point is
located at (r,g,b), sized according to the frequency, and coloured to
match the original colour.

splot "data" using 1:2:3:4 with points pointsize variable

gets me most of the way there, but the colour remains elusive. I would
be willing to sacrifice the sizing of points to get the colours right
(or overlay coloured blobs on scaled points for example)
