Re: NhlNewColor accept array argument

I agree Bruce! Unfortunately, we don't have optional argument capability in NCL, so you can't have NhlNewColor accept either 4 arguments (wks, r,g,b) versus two arguments (wks,(/r,g,b/)).

I'll add it to our list to create supplement functions that are more user friendly, maybe simply:

   i = newcolor(wks,(/r,g,b/))

You can certainly write your own using an NCL scripts. See the attached "new_color.ncl" and the "new_color_test.ncl" that calls it.
You can even choose for "new_color" to be a procedure instead of a function, if you don't need the return values.
