It is difficult to identify it (watermark, paper and different colors)
Are you sure it is Mi 336 and not Mi 223 (1948, Soviet Zone)?
If it is Mi 336, I found on "philaseiten.de" a very good example for the type of paper.
LEFT ordinary paper: - gewohnliches – "z" papier
rougher surface, paper is matt, colors not so good
RIGHT coated paper: -gestrichenes – "v" papier
smoother surface, paper shines in backlight, colors are clearer
For color, maybe the picture from the Michel Color Guide is helpful:
a = dunkelrotlila
b = lila
