New color palette [message #79609]

Hello,
I am looking for a cyan to blue to white to red to yellow color
palette similar to the one here:
http://www-meom.hmg.inpg.fr/Web/pages-perso/brankart/Ferret_ scripts/white_centered.gif.

Specifically I am looking for a 256 version of the white_centered.spk
palette from Ferret. It is my understanding that Ferret interpolates
the colors from the following:
0 0 100 100
20 20 20 100
35 100 100 100
65 100 100 100
80 100 20 20
100 100 100 0
I believe the first column is the percentage value, but I am just not
sure how to use on 6 RGB values to get a full color palette I can use
in IDL.

Any assistance would be greatly appreciated.
Thanks,
Kim
