Hi,
the nested color inherits the transparency from it's surrounding color.

Maybe intended behaviour, maybe a bug. Donno.
colorspace, color and transparency are different axis
\definecolor[colX] [r=.5] \definecolor[colY] [t=.5,a=1]
\starttext
\startbuffer \dontleavehmode \blackrule[color=colX,width=3cm]\hskip-1.5cm \blackrule[color=colY,width=3cm] \stopbuffer
\getbuffer \par \color[colY]{\getbuffer}
\setupcolors[rgb=no]
\getbuffer \par \color[colY]{\getbuffer}
\setupcolors[rgb=no,cmyk=no]
\getbuffer \par \color[colY]{\getbuffer}
\stoptext
it just happens that coming from mkii colors can have transparencies
as Alan says: they are different things (also in metafun)
\startMPcode fill fullcircle scaled 4cm withcolor "red" ; fill fullcircle scaled 3cm withtransparency (1,0.5) ; fill fullcircle scaled 2cm withcolor "green" withtransparency (1,0.5) ; \stopMPcode
Thanks for the clarification. Stupid me :D
