[ferret_users] grayscale palette

[jimmyc@xxxxxxxxxxx]

Hi All-
I need to make a color plot gray.

My values cross 0 and are NOT symmetric.
Is there a way to specify a grayscale such that the grays are skewed:
1. for the positive values go light to medium gray
2. for the negative values go medium to light
all in one palette?
Thanks for any advice.
