Can you use acrylic paint, oil paint, graphite, chalk, oil pastel, white spirit all together?
If you mix them all together you will get a disgusting gooey grey mush. However, you could use graphite and chalk for sketching. Acrylic for the underpainting. Oil paint and white spirit for various layers of paint. Finally use oil pastel to give you painting some highlights and textual effects. Good luck.
Acrylic paint, is just pigment suspended in a resin, and will stick to most surfaces, except wet oil paint. Oil paint likes an absorbent surface, but will sit on acrylic. if you mix it with white spirit, it goes very matt, but fast drying turps is better. you can even mix it with wax… Graphite is just carbon dust, and is in most black paints, the dust sticks to the surface with a weak electrostatic force, so shiny surfaces tend to be less able to hold the dust, unless it is fixed with glue rapidly (hairspray) but this will really discolour whites over time. Chalk goes transparent in oil, so you loose the image, and have to use an other white powder, like Titanium or zinc, so its easier to use the paint raw.
