colormap including gray for out of range

so i use trisurf with a color vector to display a surface colored by a parameter within a known range.

what i need is the ability to apply a known color (e.g. gray) to out of range values. is there a way to

build a custom color map which does this?

You should be able to use colormapeditor to edit the current cmap or any of the presets.

and there are lots of options on the FEX, too.
