The technique of glaze painting — applying thin transparent color layers over a dried opaque base — is a traditional oil painting technique that translates well to digital work.

What glazing achieves: luminous, deep color that you can't get from a single opaque layer. The transparency of each glaze layer means the light bounces off the layer beneath and comes back through the glaze, creating a quality sometimes described as depth of color.

Digitally: I replicate glazing using Multiply and Color layers at low opacity (15–30%). A warm yellow glaze over a cool neutral base produces a warm glow without completely changing the underlying temperature. The effect is more complex than painting the warm yellow directly.

The application sequence: base layer (opaque midtones, fully opaque), first glaze (darken shadows with Multiply at low opacity), second glaze (enrich midtones with Color layer), final glaze (warm or cool overall temperature with Overlay at very low opacity).

This sequence produces a luminosity that I can't achieve through single-pass painting.
