I use a slightly different one that I really like.
0 0 0 40
20 0 0 100
45 100 100 100
55 100 100 100
80 100 0 00
100 40 0 0
It starts with a blackish blue, goes to a saturated blue, then
to white for the middle ten percent, goes from light pink to
saturated red, then desaturates for a dark blood-red.

Subject: Re: Discontinuous color table...
There are probably more elegant solutions, but as long as you
leave the central value of the color table white, it should
always be as you want. For instance, I use the following blue-
white-red palette:
0 20 20 100
45 95 95 95
55 95 95 95
100 100 20 20
Note that the central 10% of the color range is white (actually
very light gray, you could make it white by changing all the 95's
to 100's).
Then I would fill:
fill/lev=(-3,3,1,-1)del(0) variable
This would leave the range between -1 and 1 white. Negative values
would shade from dark to light blue, then positive values from light
to dark red. If you then wanted to have a zero contour line:
contour/over/lev=(-3,3,1,-1) variable
This did the trick. Thanks, Billy!
