Mix orange paint with a small amount of blue paint until you get a brown tone
Mix red paint with a small amount of green paint to produce brown
Mix yellow ochre with burnt umber for a classic brown
Mix yellow ochre with burnt sienna for a warmer brown
Mix burnt umber with a touch of black for a darker brown
Mix burnt sienna with a touch of black for a darker, warmer brown
Start with white paint to lighten brown (use small amounts)
Use titanium white to adjust to a lighter “taupe” shade
Use a tiny amount of primary red, yellow, and blue together to darken and neutralize
Adjust warmth by adding more red/yellow (warmer) or more blue/green (cooler)
Adjust darkness by adding more burnt umber/burnt sienna or a small amount of black
Test the color on scrap paper/canvas, then refine in small increments
