Green pigments almost always exhibit extreme tinting strength. A single drop of synthetic Phthalo Green can swallow ten times its volume in organic red. Never start with equal parts; always build from the weaker pigment upward.

Pigment Combination Mixing Ratio (Red : Green) Resulting Hue & Tone
Cadmium Red + Phthalo Green 80% Red : 20% Green Deep Warm Umber / Mahogany
Cadmium Red + Viridian Green 50% Red : 50% Green Color-Wheel Neutral Chromatic Gray
Venetian Red + Sap Green 30% Red : 70% Green Earthy Khaki / Muted Camouflage Green
Alizarin Crimson + Phthalo Green 45% Red : 55% Green Velvety Chromatic Black / Deep Shadow Charcoal

To control your values precisely, deposit a nickel-sized pool of red onto your mixing surface. Using the corner of a palette knife, lift a pinhead-sized fleck of green into the edge of the red puddle. Blend thoroughly until streaks vanish. Check the swatch against white watercolor paper or a primed canvas board to evaluate undertone clarity before adding another micro-measure of green.
