Matlab Colormaps
There are a lot of color maps available using the NCLcolormap script within matlab:
load nclcolormap
I’ve made a document on what they all look like. Right click to open in a new page so you can scroll/zoom easier. Find one you like and use it by typing:
colormap(nclcolormap.{NAME})
where NAME is shown undernearth the horizontal colorbar on the figure below.
