I have this small test case:
[-- Attachment #2: test.tex --]
[-- Type: application/x-tex, Size: 798 bytes --]
[-- Attachment #3: Type: text/plain, Size: 205 bytes --]
and it comes out with the wrong colors. So, I think I know that this
is because of the same dimensions but I want to have different colors
for the same overlay-dimensions. How do I do that?
bye, Adam.

Here is another approach
% small extension to underbar, accepts [settings]
\unprotected \def\underbarparameter#1{\getvalue{\??on#1}}
\unexpanded\def\dounderbar#1%
{\let\betweenisolatedwords#1%
\dosingleempty\redounderbar}
\unexpanded\def\redounderbar[#1]#2%
{\iffirstargument\setupunderbar[#1]\fi
\processisolatedwords{#2}\dodounderbar
\egroup}
% roughly the same
\startuniqueMPgraphic{underline}{color,width,height,depth}
numeric w,h; w := \MPvar{width} ; h := \MPvar{height} ; d := \MPvar{depth} ;
path p; p := (0, -h)..(w/2,0 + (h/3 randomized h/3))..(w, -h);
p := p shifted (0,-d) ;
draw p withpen pencircle scaled 1 withcolor \MPvar{color} ;
setbounds currentpicture to unitsquare xyscaled
(OverlayWidth,OverlayHeight); \stopuniqueMPgraphic
hook into underbar:
\unprotect
\def\underbarmethodx#1#2#3% mp
{\hbox to #1{\uniqueMPgraphic
{underline}{width=#1,height=#2,depth=\underbarparameter\c!bottomoffset,color=\underbarparameter\c!color}}}
\protect
% usage:
\setupunderbar[alternative=x,bottomoffset=1ex,color=red]
\startitemize
\item test: \underbars[color=blue]{how are you?}
\item test: \underbars{how are you?}
\item test: \underbars{how are you?}
\stopitemize
\stoptext
in your case, in order to make the graphic unique, you need to pass the second
arg in order to make them unique (uniqueness is determined by dimensions and a
few more things; another option would be to use the backgroundcolor of inframed
which is accessible by \OverlayColor and also determines uniqueness
\startuniqueMPgraphic{underline}{color}
alternative
\startuniqueMPgraphic{underline}
numeric w,h; w := OverlayWidth; h := ExHeight/6;
path p; p := (0, -h)..(w/2,0 + (h/3 randomized h/3))..(w, -h);
draw p withpen pencircle scaled 1 withcolor OverlayColor ;
setbounds currentpicture to unitsquare xyscaled
(OverlayWidth,OverlayHeight); \stopuniqueMPgraphic
\defineoverlay[underline][\uniqueMPgraphic{underline}]
\def\aidul{\dosingleempty\doaidul}
\def\doaidul[#1]{\inframed[background=underline,frame=off,#1]}
\setupcolors[state=start]
\startitemize
\item test: \aidul[backgroundcolor=red]{how} \aidul[color=green]{are}
\aidul[color=blue]{you?}
\item test:\aidul[backgroundcolor=blue]{how} \aidul[color=green]{how}
\aidul[color=red]{how}
\stopitemize

Thanks for the fast response and the many lines you've written
(although I didn't understand everything). The OverlayColor works
fine and as underlining is in the background, I'll take this aproach.
So, one last question remains: why doesn't this work?
\def\uli{backgroundcolor=peachpuff} \aidul[\uli]{test}
bye, Adam.

parsing ....
\def\doaidul[#1]{\expanded{\inframed[background=underline,frame=off,#1]}}
would work
however, in that case i'd go for:
\def\doaidul[#1]{\inframed[background=underline,frame=off,backgroundcolor=#1]}
\definecolor[important][red]
\definecolor[notimportant][green]
and \aidul[important]{test} as well as \aidul[notimportant]{test} since one can
redefine the colors
