What it says; you can't use both "color" and "rules". If you use
"color=rules", the rules are read from stdin (equivalent to -i). If
you use "rules=...", the rules are read from the specified file.

So, just omit the color=rules option, i.e.:

r.colors map=b25_daymax0.l1_neu at PERMANENT 'rules=/sonne3/.../GIS/colorscript_farben_temp'
