"Cobalt Pigment"
Cobalt Pigment refers to a group of inorganic pigments made from cobalt-based compounds, most notably Cobalt Blue (PB28), Cobalt Green, and Cobalt Violet. These pigments are prized for their subtle granulation, color stability, and moderate opacity. Cobalt pigments have excellent lightfastness and maintain consistent chromatic behavior under different lighting conditions, unlike more fugitive alternatives.
They are ideal for skies, shadows, and color mixing in oil, watercolor, and acrylic applications. Due to their heavy metal content, cobalt pigments are more expensive and require careful handling.
Nonetheless, their clarity, permanence, and versatility make them a favorite among professional artists.
