Clear colormap for figures when printed?

I often produce figures with a surface with quantitative data attached, plotted in a heatmap type style (see figure).

Previously, I've used the default matlab colormap for this but I recently noticed how terrible this is when printed black & white, the high and low colors appear the same.

Is there a better/recommended colormap I should use to improve clarity when printed.
