Colormap is based on the colors used by W. F. Haxby's Gravity field of World's oceans, 1985, developed for geoid and gravity maps. The version used here is formed from a linear interpolation of the GMT color table used by MB-System by David W. Caress and Dale N. Chayes (http://www.ldeo.columbia.edu/res/pi/MB-System).
