It works but in normal text but if you use MetaPost graphics
only the first text is transparent.

\setupcolors[state=start]

\definecolor[tred][a=1,t=.5,r=1]

\starttext

\startluacode
tex.sprint("\\startMPcode")
for i=1,5 do
     tex.sprint('label(textext("\\definedfont[Sans sa ' ..  
math.random(1,4) .. ']%')
     tex.sprint('\\color[tred]{1}"),(10*' .. i .. ',0)) ;')
end
tex.sprint("\\stopMPcode")
\stopluacode

\stoptext
