Reported by FlipGer confirmed by ronilse:

If you enable view genre as colour in MP setup, it doesnt show that in TV or Radio Guide when opening inside MP.

To reproduce:
Enable use colors for genres in the TV Guide in MP Setup -> Television -> Program Guide. Open MP & go to television & TV Guide, no colours for different genre shows.

h4. Additional Information
Fix (I think :-) ):
As FlipGer stated the errors lies in GUITvGuideBase.cs & GUIRadioGuideBase.cs (me later), theyre referring to "_colorList", which in this case in mediaportal.xml is set as "colors" by TVProgramGuide.cs.

If the line 196 in GUITvGuideBase.cs _useColorsForGenres = xmlreader.GetValueAsBool("xmltv", "_colorList", false);
Its change to _useColorsForGenres = xmlreader.GetValueAsBool("xmltv", "colors", false);

& line 195 in GUIRadioGuideBase.cs _useColorsForGenres = xmlreader.GetValueAsBool("xmltv", "_colorList", false);
Its change to
        _useColorsForGenres = xmlreader.GetValueAsBool("xmltv", "colors", false);
