Re: [ferret_users] Creating difference plots with white in the colour bar
Same idea as Ryo (but I think not as intense colors at the ends). My
opinion, it's better to have a light gray not white at the center of
the range, so you can distinguish blanks (islands or land) from zero
values.
It's easy to make these palettes; do them on the fly and experiment.

Hi everyone,
I am trying to plot the difference between two global temperature
fields.
e.g.
fill/lev=(-inf)(-5,5,1)(inf)/palette=blue_darkred
temp_mm_1_5m[d=1,l=1] - temp_mm_1_5m[d=2,l=1]
Where the difference is less than 0.5 degrees Celsius, I wanted to
shade the area in white - to imply that the difference is not
significant. For consistency with earlier work I would ideally like
to incorporate white into the blue_darkred palette.
Does anyone know a simple way of doing this? Or what combination of
RGB colours make up blue_darkred do that I could try and create my
own palette?
Apologies if this is obvious, but I am a ferret novice!
Thanks in advance,
Aisling
