Hello,
I've a problem with color specifications in Plot.
I take a simple example to explain.
Let consider:
In[1]:=Plot3D[ x^2+y^2 ,{x,0,1} ,{y,0,1}, ColorOutput-> RGBColor]
This works fine.
If I try (as I need):
In[1]:=Plot3D[ x^2+y^2 ,{x,0,1} ,{y,0,1}, ColorOutput-> None]
this gives the error message:
ColorOutput::colpc:
Result None[GrayLevel[0.]] obtained during color
conversion
by applying function None to color GrayLevel[0] is not a
GrayLevel, RGBColor, or CMYKColor color directive.
What does it means?
How can I avoid this problem?
Thanks,
Nicola
