Most  of the Physarum I have obtained through moist chamber cultures have all been yellow in color, however, I read where the color can sometimes be due to the pH of the substrate on which the plasmodium resides.  Again, however, nothing here has changed from the substrate used to culture the yellow plasmodia and yet it has produced a bright red to an orangish-red plasmodium.  The substrate as already mentioned was, the bark of a Flowering dogwood tree.
