\definecolor[MyColorA][r=0.8784, g=0.8784, b=0.8784]

\defineframedtext
   [MyFrame]
   [frame=off,
    background=MyFrame,
    width=6cm,
    height=fit,
    style=small]

\startuseMPgraphic{MyFrame}
     path b;
     picture p;
     p := textext.rt("\tfx\white\framedtextparameter{Title}");
     p := p shifted (2BodyFontSize,OverlayHeight-ypart center 
p+.25ExHeight);
     b := boundingbox p leftenlarged .5EmWidth rightenlarged .5EmWidth ;
     fill OverlayBox withcolor "MyColorA" ;
     fill b withcolor darkred ;
     draw p ;
     setbounds currentpicture to boundingbox currentpicture enlarged 2mm ;
\stopuseMPgraphic

\defineoverlay
   [MyFrame]
   [\useMPgraphic{MyFrame}]

\starttext

     \startcombination[2*2]
         {\MyFrame[Title=ALGO A]{One}}   {}
         {\MyFrame[Title=ALGO B]{Two}}   {}
         {\MyFrame[Title=ALGO C]{Three}} {}
         {\MyFrame[Title=ALGO D]{Four}}  {}
     \stopcombination

\stoptext

the start/stop variant ignores the width
