Chromium Green Oxide — PG 17

Virgil’s assessment: Chromium oxide green is opaque and fairly lean, with higher tinting strength than terre verte. It works particularly well for verdaccio underpainting in mixtures with lead white.  Useful in portraits and landscapes. [Included in his portrait palette.]

Viridian — PG 18

Virgil’s Assessment

Vasari Viridian is sometimes found on Virgil’s palette.

This color is considered brighter and more transparent than PG-17 (Chromium Oxide Green), but weaker in tinting strength.

Green Earth — PG 23

Virgil’s Assessment

Also known as Terre Verte or Verona Green.

Terre vert is a natural earth color, transparent and low in tinting strength, high in oil content. Unfortunately, many paint companies are calling various mixtures of other colors by that name, which just creates confusion. Real terre vert is not a mixture of any other pigments.

Virgil uses Rublev’s Verona Green Earth.

Phthalocyanine Green– (Pigment number depends on shade)

Virgil’s assessment:

Virgil’s primary use for phthalocyanine green (phthalo green for short) is in mixes for substitutes for problematic pigments.

For example:

  • For Burnt Umber: he mixes phthalo green with Mars Brown
  • For a more transparent Burnt Umber:  phthalo green with transparent oxide red
  • For Raw Umber: the above mixes with more phthalo green

Note that phthalo green has a very high tinting strength, so very little of it is needed in mixtures.  It has a high chroma and is heavily staining.
