[GRASS-user] Precipitation color table?

[Luigi Ponti]

Dear Markus,

I just ran into this page
http://geography.uoregon.edu/datagraphics/color_scales.htm

that includes, among others, precipitation color tables. I don't know if 
that can be useful.

The page of this Lab also provides an interesting paper titled "End of 
the Rainbow" which elaborates on why one should not use continuously 
varying color schemes (and absolutely no rainbow color table). The way 
to go seems to be banded color schemes -- a color scheme with equally 
sized bands of constant color [1].

As I side note I was wondering how to draw such a color scheme (i.e. 
with equally sized bands of constant color) in GRASS.

Kind regards,

Luigi
