See Wolfgangs answer.
If your using lmtx ...
\startuseMPgraphic{MyFrame}
picture p ;
p := lmt_text [
width = OverlayWidth,
height = OverlayHeight,
text = "\bfx\framedtextparameter{Title}",
color = "white",
align = "normal",
] ;
p := anchored.ulft (p, ulcorner OverlayBox shifted (0,EmWidth)) ;
fill OverlayBox withcolor "MyBlue" ;
fill boundingbox p enlarged .5EmWidth withcolor "maincolor" ;
draw p ;
setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic
watch how also maincolor is accessed as string.
Hans

Hi Hans,
Some time ago, you offered this code to respond to a specific request from
me. I used this code again and wanted to know if it was possible for the
title "Algorithm" to be automatically centered based on the content.
