Cobalt Blue - An Iconic Blue
PB28 - Semi-transparent - Granulating
Ideal for landscapes, Cobalt Blue excels in skies, calm waters, and distant mountains. Its granulating nature is perfect for textured effects and organic details.e. Bright and close to primary blue. We can define it as the most blue of blues because it does not draw on green (like Prussian blue) or red (like overseas).
