Things You'll Need
Instructions
Lay out 1 tbsp. each of the red oxide, black, burnt sienna, cadmium red and white on your mixing surface or palette.
Mix about 1 tsp. of the black into the white. Smear it about with the palette knife. The flexible blade of the knife makes it easier to blend acrylic colors than if you employed regular knife or spatula. Mix until you have an even gray.
Mix 1 tsp. of your gray hue into the red oxide. Again, blend well.
Review your color. If you have the brick color desired, stop. If not, you must adjust it.
Add 1 tsp. of cadmium red for a more brilliant red brick. Add 1 tsp. of burnt sienna for an earthier color. Add more gray for a neutral red, one that looks less colorful. Add a tiny speck of black to darken the brick hue.
Continue reviewing your brick color, measuring it against your brick subject. Use smaller amounts of color as you approach your target. Sticking the end of the palette knife into the dab of acrylic paint on your palette, then quickly removing it, will leave a trace of color on the palette knife that is just right for small adjustments.
