>>6103997after some more experimenting, it seems that the black pastel I used has very potent staining characteristic. I used a more earth-tone black pastel on my char back there and the staining was very minimal (on white plastic, actually kind of pleasing) or not noticeable at all (on the char MS).
This could've all been avoided if I had just used acrylic _(:3/<)_
Everyone tells me they like the blue tint on the legs but I hate it
