Hi,

1. In the following code, the color is not included in the \startframedtext \stopframedtext environment

Remove the \MPcolor command, it is only needed for meatiest graphics. You can also remove \setupcolors[state=start] because MkIV enables colors by default.

2. How can the height of the red square adapts to the height of the text ?

You can use the \htofstring command to get the height of a character but the command accepts only text and you can’t use color or font settings in the argument.

3. Can we improve the code ?

Use keys to set the colors for all elements, you can also remove the \feature command because settings small caps for uppercase text is useless. You should also create a real command for the headcommand key because there can be problems when context checks for the value of the key. \definecolor[mycolor][c=0.00, m=0.10, y=0.20, k=0.00] \define\DefinitionHeadcommand {\blackrule [ color=red, width=\htofstring{D},% width=\htofstring{\enumerationparameter{text}}, height=\htofstring{D}]% \thinspace} \defineenumeration [definition] [text={DÉFINITION : }, headstyle=bold, headcommand=\DefinitionHeadcommand, headcolor=blue, titlecolor=red, width=fit, alternative=top, title=yes, titleright=, titleleft=, before={\startframedtext[width=\textwidth,frame=off,background=color,backgroundcolor=mycolor]}, after={\stopframedtext}] \starttext \startdefinition{Expérience aléatoire} Une {\bf expérience aléatoire} est une expérience renouvelable dont les résultats possibles sont connus sans qu'on puisse déterminer lequel sera réalisé. \stopdefinition \stoptext Wolfgang
