How do you color Styrofoam?

To color Styrofoam, you can use spray paint, which provides an even coat, or acrylic paint, applied with a brush or sponge for more detailed designs. Before painting, it's helpful to lightly sand the surface to improve paint adhesion. Always ensure you're working in a well-ventilated area and consider using a primer designed for foam if you're applying multiple layers for a more vibrant finish. Allow the paint to dry completely before handling.
