So I was aware that sprites could be applied an ImageFilter which gives a color tint but is it possible to overlay the sprite with a solid color?
I am not sure what you are trying to achieve would you have a visual ?
I apologize for the terrible description.

You would need to process your image with a custom shader for it. Maybe it would be simpler to dupplicate it in your sprite texture and keep a white shape so the tint would work exacty like this ?
