Red Plus Green Paint Mixing Fact-Check: Light Physics Vs. Physical Pigment
The differences between optical light mixing and material pigment blending can be mapped across primary color models, industrial applications, and visual outcomes:
| Mixing Environment | Governing Model | Red + Green Result | Primary Mechanism |
|---|---|---|---|
| Stage Lighting / OLED Screens | RGB (Additive) | Bright Yellow | Wavelength emission stimulating L and M cones |
| Studio Painting (Acrylic / Oil) | RYB (Subtractive) | Warm Brown to Deep Earth | Subtractive pigment absorption and binder scatter |
| Offset Commercial Printing | CMYK (Subtractive) | Muted Khaki / Dark Olive | Layered transparent dot absorption over white paper |
| Industrial Optical Sensors | Spectrophotometry | Broad Spectral Attenuation | Reflectance curve drops across 400, 700 nm |
