It's even more weird than that. The colour of the first item behind
the "dark" depends on the colour of "light":
\usemodule[tikz]
\definecolor[extralight][s=1,a=1,t=0.1]
\definecolor[light][s=1,a=1,t=0.6]
\definecolor[dark] [s=1,a=1,t=0.95]
\defineframedtext[normal] [width=6cm, background=color]
\defineframedtext[reverse][width=6cm, background={foreground,color}]
\startbuffer
\tikz\fill[color=blue] (0,0) circle (.2cm);%
\startMPcode fill fullcircle scaled (.4cm) withcolor \MPcolor{blue}; \stopMPcode
\tikz\fill[color=blue] (0,0) circle (.2cm);
\stopbuffer
\starttext
\startnormal[backgroundcolor=light] \getbuffer \stopnormal
\startnormal[backgroundcolor=dark] \getbuffer \stopnormal
\blank[2*line]
\startreverse[backgroundcolor=light] \getbuffer \stopreverse
\startreverse[backgroundcolor=dark] \getbuffer different \stopreverse
\blank[2*line]
\startreverse[backgroundcolor=extralight] \getbuffer \stopreverse
\startreverse[backgroundcolor=dark] \getbuffer from this one \stopreverse
\stoptext
