Here is a step-by-step guide on how to mix acrylic paint:

1. To mix acrylic paint with water, the ratio is usually two parts paint to one part water.
2. To mix acrylic paint with pouring medium, the final mix should run like warm honey, motor oil, or chocolate syrup.
3. To mix acrylic paint with latex paint, pour the thinned acrylic into the latex paint container and stir them.
4. To mix acrylic paint with other colors, use a paint tray and a brush to blend them well.
5. To blend acrylic paint on the painting surface, use the wet-on-wet technique by applying both paint and water to the wet surface.
