What Happens When You Mix Green and Blue? the Surprising Color Theory Behind Teal and Cyan
By Alexander Ross
Paint formulas rarely contain pure, idealized wavelengths. Pigments are mineral and synthetic chemical compounds, each carrying inherent warm or cool undertones that drastically manipulate the final paint blend.
An artist working with French Ultramarine faces an immediate chemical complication: Ultramarine contains subtle red undertones, making it a warm blue. Mixing Ultramarine with a warm green like Olive Green, which carries red-leaning yellow pigments, introduces all three primaries into the cup. The result is not a luminous peacock teal, but a desaturated, earthy slate. Conversely, using Phthalo Blue (a cool, green-leaning copper phthalocyanine) alongside Phthalo Green generates hyper-saturated, electric teal shades because both pigments share matching clean cool bases.
| Target Color | Starting Ratio (Green to Blue) | Recommended Pigment Pairings | Chromodynamic Behavior |
|---|---|---|---|
| Electric Cyan | 1:1 (Plus 70% Titanium White) | Phthalo Blue (PB15:3) + Phthalo Green (PG7) | Reflects maximum short-wave cyan light; zero muddying. |
| Classic Deep Teal | 1:3 (Blue Dominant) | Prussian Blue + Viridian Green | Deep, velvety absorption with high tonal depth. |
| Vibrant Turquoise | 2:1 (Green Dominant, Tinted) | Cobalt Green + Cerulean Blue | Opaque, semi-chalky natural mineral finish. |
| Moody Seafoam / Aquamarine | 3:1 (Green Dominant, High White) | Terre Verte + French Ultramarine | Subdued, desaturated tone ideal for atmospheric perspective. |
