Silk Screen Print Andy Warhol Grid

Transform this photo into a 2x2 Andy Warhol silk screen print grid. Each panel uses the same face but with different bold pop art color palettes: hot pink and yellow, electric blue and orange, lime green and red, purple and gold. Apply the classic Warhol screen print texture with visible halftone dots, slightly misregistered color layers, and high contrast shadows. The background of each panel should be a flat, saturated color. Keep the person's face and expression exactly the same across all four panels. The overall feel should be iconic, gallery-worthy, and authentically Warhol.
