Description

Indanthrone Blue (P.B. 60) is a luxurious, deep blue pigment with a warm undertone, known for its dramatic intensity and refined elegance. Often described as an “inky blue,” this watercolour offers artists a beautifully rich and velvety tone ideal for painting moody skies, tranquil waters, and atmospheric shadows. Its unique warmth sets it apart from cooler blues, making it especially valuable for creating depth and emotion in landscape and abstract compositions.

This pigment is **transparent** and features a **low staining strength**, allowing for controlled layering, subtle transitions, and soft blends. When diluted, Indanthrone Blue shifts into softer, muted tones, ideal for delicate glazes, foggy backgrounds, and serene lighting effects. Its strong tinting strength enhances colour mixes, creating rich purples with reds and forest-like greens with yellows, adding depth and nuance to every palette.

Indanthrone Blue is highly lightfast (AAA), ensuring your artwork remains vibrant and true over time. Its smooth flow, excellent mixing potential, and balanced warmth make it an essential pigment for both expressive and precise painting styles. Whether used solo or in combination, this sophisticated blue helps artists bring richness and complexity to their work.
