That I spotted and corrected, but I'm getting another error, I suppose:

Change "with color" to "withcolor" (no space).
Here is a more detailed example that mimics the tikz code that you sent in
the other email.

In ConTeXt, if you put quotes around the name of a color, it looks at the
colors defined in tex rather than colors defined in metapost. This allows
you to easily share the same colors in text and figures.
As an elegent example of this see this excellent imitation of Byrne's
Euclid:
