"This is a very complicated case, Maude. You know, a lotta ins, a lotta outs, a lotta what-have-yous." 
(Jeffrey 'The Dude' Lebowski)

 \color[<colorname>]{<text>}

is valid but you use \color without the text. To fill the missing argument context uses now the following command after \color or in some cases internal macros.

I see now, it’s here: http://wiki.contextgarden.net/Command/color


Another thing which doesn’t work in MkIV are these lines:

\definetypeface[tSCIRMA][rm][Xserif][Palatino]
\definetypeface[tSCIRMA][tt][Xmono][LM Typewriter Regular]
\definetypeface[tSCIRMA][ss][Xsans][Optima]



Yeah, I had already replace with simplefonts module

Best
