Re: [ferret_users] need help for color palette



I have had good luck with using a palette based on levels when I need to be really picky about a color palette.  Here is one that I setup for representing Palmer Drought Index that may be helpful.  I've included it in the email below in case it doesn't arrive attached.

! Set the type of palette
RGB_Mapping By_value

! Paleo PDSI Scale by Value

Dear ferreters,

I need to remove purple color from the default color palette (i.e., from hottest DARK RED to coldest DARK BLUE, no purple color but keep orange, yellow and green). Would anyone please share a *.spk and attach it here? In ppl directory, I can find no_green_center.spk and no_blue_center.spk but they are only with two colors, red&blue or red& green.

Thank you very much for your help!
Haoping
