[NTG-context] use color in XeTeX+ConTeXt

[Dalyoung Jeong]

Dear all,

In ConTeXt, the following example was shown in colors.

\setupcolors[state=start]

\starttext

The use of color in \TeX is not {\red easy}.

{\blue What color is it?}

\stoptext

but, the same text after defining new typescript and saved for XeTeX 
+ConTeXt, the colors were gone. It is possible to change color using  
following method:

	\special{color push}
	\special{color rgb 0.0 0.5 0.8}
		sample text
	\special{color pop}


However, is there a simpler way to use color in XeTeX+ConTeXt as in  
ConTeXt?

Thank you

Dalyoung
