[ferret_users] need help for color palette

[Haoping Yang <haoping.yang@xxxxxxxx>]

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!
