The \page command is needed here.

You can use the \pushbackground and \popbackground command to limit the 
background changes to a certain part of your document.

\defineheadalternative
   [partpage]
   [renderingsetup=partpage]

\startsetups[partpage]

     \startmakeup[part]
         \headsetupspacing
         \headnumbercontent
         \blank[big]
         \headtextcontent
     \stopmakeup

\stopsetups

\definemakeup
   [part]
   [align=middle,
    top=\vfill\vfill,
    bottom=\vfill\vfill\vfill]

\setuphead
   [part]
   [placehead=yes,
    alternative=partpage,
    page=right,
    
before={\pushbackground[page]\setupbackgrounds[page][background=color,backgroundcolor=blue]},
    after={\page\popbackground},
    bodypartlabel=part,
    align=middle,
    numberstyle=\bfb,
    textstyle=\bfd\sc]

\setuplabeltext[en][part=DĂl ]

\starttext
   \part{Part}
   \input knuth
\stoptext

BTW: Where is Ad 2?
