Scrambed LUT

Hello--
 
I have an RGB image that I'd like to convert to an 8-bit color image but
with an unscrambled LUT. By unscrambled, the colors are organized based on a
spectrum or colors sorted using an equation like the histogram's gray
formula (gray=0.299red+0.587green+0.114blue) or similar. I can't seem to do
this with ImageJ's built-in converter; the resulting LUT is scrambled. I
know converting to 8-bit grayscale unscrambles the LUT, but then I lose the
color information.
 
I want to do this so I can apply a threshold to darker areas of the image
for later measuring.
 
Any ideas?
 
Thanks,
Aaron
