Cad. Red Replacements

Pyrrole Pigments

1. Pyrrole Red (PR254)

Kremer Pigments

2. Pyrrole Scarlet (PR255)

Kremer Pigments

3. Pyrrole Red Deep (PR264)

I’ve been using Geneva Pyrrole Rubine and am happy with it overall. However, I think its value is too dark to effectively capture brightly lit red objects.

Kremer Pigments

Naphthol Pigments

Generally poor lightfastness compared to other modern pigments.

4. Naphthol Red AS-D (PR112)

5. Naphthol Red F5RK (PR170)

6. Naphthol Scarlet (PR188)

Quinacridone Pigments

7. Quinacridone Red (PR209)

8. Quinacridone Magenta (PR122)

Inorganic Alternative

Doesn’t seem to have uses for oil painting.

9. Cerium Sulfide Red (PR265)

Venetian Turpentine

In the strict botanical sense, Venetian (Venice) Turpentine is not a balsam but an oleoresin—the viscous exudate from the larch tree ( Larix decidua ) that contains both volatile “turpentine” oils and non-volatile resinous solids.

However, historical painting manuals and some suppliers have loosely grouped it with the balsams (especially Canada balsam), since it behaves similarly as a viscous, fixative-type medium in oil painting. For example, Rutherford Gettens and George Stout’s Painting Materials: A Short Encyclopedia actually lists Venice Turpentine under “balsams”, even though Frederic Hyde’s Solvents, Oils, Gums… treats it as a solvent—reflecting the overlap in practical use more than strict chemical classification (Natural Pigments, Darwin Price).

Why it Matters in Painting

Bottom Line

Venetian Turpentine is properly an oleoresin—not a true benzoic/cinnamic “balsam”—but in painting practice it’s often treated alongside balsams for its viscous, fixative properties.
