Art Brushes appear grey, and not Rich Black.

Question

Art brushes are showing a grey version of what should be a Rich Black RGB 0, 0, 0,. Furthermore, expanding the art brush stroke and sampling the color shows the strokes "Black" is actually: 32,32,32, pre-expansion the RGB sample shows the stroke is 0,0,0.
Color Mode=RGB
Print Proof=NO
Document =RGB
Display all Blacks, print all Blacks=Rich Black

Answer 1

Try this.
Use one of the Chalk and Charcoal brushes, like Charcoal - Feather.
Set the colorization method to NONE.
Make a mark. Take a sample reading with the Eyedropper tool. The RGB value will be, 32,32,32 (or some place around there) but defiantly not 0,0,0.
Now EXPAND the stroke and take a reading of the shapes color. Same values.
It is NOT RICH BLACK.
I DO NOT understand emils directions.
