You really are stretching tex to the limits now -)
The rather low level and cross you fingers approach is:
\setupbackgrounds[page][background=screen,backgroundscreen=0]
\starttext
\dostartnegative
\externalfigure[test.pdf][page=1,height=10cm]
\dostopnegative
\stoptext
Alternatively, you can first negate the original.
