Error with adding color using NhlNewColor

Hi all,

I am trying to use the NhlNewColor to add grey to an existing color map. I
have done this in previous scripts but for some reason in my current scrip I
am getting a fatal error when try the following:

  gsn_define_colormap(wks,"BlueWhiteOrangeRed") ; define a different
colormap.

  igrey = NhlNewColor(wks,8,.8,.8) ; Add light gray to colormap,
                                                          ; for continents.

giving me the error:

*fatal:_NhlNewColor:no available colors*

I am currently running ncl version 6.0 beta on a Macbook Pro.

Any help or suggestions would be greatly appreciated.
Gina.
