Re: [ferret_users] a paletter with only red (pink) and blue and white centered

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi -
We'll add Ryo's palettes to the ones that come with Ferret - they're a 
bit similar to the blue_darkred palette already included, but with a 
somewhat different range of reds, and having options for no-white at the 
center is good.

I also want to point out for the original question, the tool Fpalette 
for searching the palettes that are included with Ferret.  From the Unix 
command line,

> Fpalette red
* * * * * * * * in /home/users/tmap/ferret/x86_64-linux/ppl
blue_darkred.spk:
centered.spk:
darkred_blue.spk:
inverse_redscale.spk:
light_centered.spk:
low_red.spk:
narrow_light_centered.spk:
...

(where of course the search for "red" finds the word "centered" in 
palette names as well as the color red).

There are also several of FAQ's on palettes, which show some of the 
palettes and what they're good for.  This FAQ,
http://ferret.pmel.noaa.gov/Ferret/faq/ferret-color-palettes

has links to several more FAQ's on particular topics.
