Place drop cloths over the floors and counters in your kitchen. Wipe the walls clean with a damp sponge.
Pour white paint into a large bucket. Add powdered pigments to make the shade of your choice. Wear a respirator when using dried pigments. Avoid using toxic artists' materials like cadmium and cobalt. Blend the pigments with the paint using a stir stick.
Apply paint to areas next to the ceiling and trim with an angled brush. These brushes give you more control and will help you keep paint off surrounding surfaces.
Use a wide, stiff brush to apply the wall paint. Apply the paint in all directions. Visible brushstrokes and other imperfections help mimic the rough, antique plaster found in authentic French Country kitchens.
Allow the walls to dry. Decide if you want to apply a second coat of paint. Using a single coat of paint will create an uneven, whitewashed look. Two coats of paint provide more complete coverage.
Wash the brushes with soap and water. Shake excess water out of the bristles. Smooth the bristles back into shape.
