brightness temperatures.

How many steps?
For 10 steps:

set rgb 80 0 0 0
set rgb 81 25 25 25
set rgb 82 50 50 50
set rgb 83 75 75 75
set rgb 84 100 100 100
set rgb 85 150 150 150
etc....

for any number of steps:

gradient = 255 / steps

n=1
colornumber= appropriate color scale start number
while (n<=steps)
'set rgb 'colornumber' 'n * gradient' 'n * gradient' 'n * gradient'
n=n+1
colornumber=colornumber+1
endwhile
