Hi John,
you can define a color for the transparent background of the text and
place it with the cover text at the background.
\setupcolors[state=start]
\setupexternalfigures[location=global]
\definecolor[coverred][r=1,a=1,t=.5]
\defineoverlay[coverimage][\overlayfigure{mill}]
\definelayer
[covertitle]
[width=\paperwidth,
height=\paperheight]
\setlayerframed
[covertitle]
[hoffset=0cm,
voffset=8cm]
[frame=off,
width=\paperwidth,
height=6cm,
background=color,
backgroundcolor=coverred,
align={middle,lohi}]
{\tfd Cover Text}
\starttext
\setupbackgrounds[page][background={coverimage,covertitle}]
\startstandardmakeup
\stopstandardmakeup
\stoptext
