Drawing a simple color bar...

  

Dear all 

I have been working successfully with GMT4 for a while.


Today, I needed to test a few selected color shades for a palette and
wanted to look at such color shades on the bar itself, 

to check if the
shades of the same color looked really different on the screen.


Surprisingly, psscale is NOT working and I have NOT been able to find
out what is wrong with the simple comand... 

I am attaching two files:
the file with RGB codes and the file with the shell script. 

I would
appreciate if someone could tell me what I am missing or doing wrong.


Thanks very much for the kindness of your help.
