"I invite the reader to try mixtures of ultramarine blue or any cobalt,manganese, chromium or "transparent" iron oxide (PR101 orPY42) pigments with any synthetic organic pigment (especially a quinacridone or phthalocyanine), or with titanate or "magnetic" brown (PBr11) or black (PBk11) pigments. Using these "modern" pigment mixtures permits a variety of water texturing effects, much better control in washes, and a much larger color gamut."

Lamp black by DS shows some granulation in wet application.

Neutral tint is typically used to dull and darken paints, and to provide a shadow color, without changing the apparent hue of mixtures; it also makes an effective stormy sky color, modulated by added blue or violet.

All cobalt paints reflect a noticeable amount of "red" light, making for warm yellows, violets and blues, but rather dull greens and turquoises.

Cyan blue copper carbonate, called blue verditer or bice, is the synthetic form of azurite. It played a minor role in artists' colors in the 18th and 19th centuries (it has a relatively low tinting strength, and was more commonly used as a housepaint).

Antwerp blue is a lighter, greener and less lightfast pigment than Prussian blue (PB27).

With a few exceptions (Bloodstone Genuine, Hematite, Serpentine Genuine, Zoisite Genuine), the paints will lift completely from paper, like a conventional cobalt violet (PV14).

M. Graham prussian blue is one of the greenest shades, slightly lighter valued than the rest and very active in wet applications; it has a noticeable pigment texture or flaking with good lightfastness. Daniel Smith prussian blue is by contrast slightly redder, darker and more saturated in masstone, with an exquisite subtle texture and good lightfastness. Winsor & Newton prussian blue is made from an especially fine textured pigment: it is the most saturated, provides good darks and handles well in all applications (it is relatively less active wet in wet but backruns readily); but unfortunately it faded slightly in masstone, lightening by about 2% in one week.
