I was just getting my head round 24-bit, having been prompted by this
thread. So, at Philip's suggestion I went to

http://www.dfanning.com/tips/colors24.html

All well and good. Sounds relatively straightforward.

So on my SGI (IRIX 6.5.1, IDL 5.1) I tried some of the
suggested code (immediatley after starting IDL up):

device,decomposed=0
tvlct,[[255],[255],[0]],100
plot,randomu(10,10),color=100

expecting the plot to be yellow, as advertised. Except no, _I_
get a medium-light shade of grey!

Any suggestions?

Andy
