Immanuel -
I don't believe you can associate a color with a TclVar,
but you can use tkconfigure to change the color of a label.
Does this little program help?
library(tcltk)
base = tktoplevel()
lab = tklabel(base,text='correct',foreground='green')
tkpack(lab)
red =
function(...)tkconfigure(lab,foreground='red',text='wrong')
green =
function(...)tkconfigure(lab,foreground='green',text='correct')
tkpack(tkbutton(base,text='Red',command=red))
tkpack(tkbutton(base,text='Green',command=green))
