LoadCT, 0, NColors=250
TVLCT, FSC_COLOR(['teal', 'dark green' 'plum','khaki'], /TRIPLE), 250
I_1 = Where(image ...)
I_2 = Where(image ...)
...
scaledImage = BytScl(image, Top=249)
scaledImage[I_1] = 250 ; teal
scaledImage[I_2] = 251 ; dark green

You can probably spot the pattern evolving here... :-)

Cheers,

David
