Colormap Stark #matlab colorbar

I wanted to have a colormap which had a great degree of contrast, and was not really a rainbow scheme.

I have tried to solve this issue by poking at different colormaps

(very close, but keeps the rainbow defect flat intensity for the large part in the middle.)
http://usefulcodes.blogspot.com/2015/06/colormap-goofy-matlab.html
(looks green and goofy! Did not like it.)

(has nice monotonic intensity gradient, but not that beautiful on maps.)
See the examples: http://usefulcodes.blogspot.com/search/label/colormap
I present you a new one! Colormap "stark".
This does have the defect of not linearly increasing the intensity, but does not stay flat in the middle. It has two saddles, allowing the left/right contrast. I like it so far.
Well, it is inspired from the LST image from MODIS

It adds whiteness in the middle, creating W shaped swing to the green pallets.
