The Caran d’Ache Classic Gouache Tube in Ultramarine (2001.140) supplies 10 ml of intensely pigmented, artist-grade blue paint. Its water-based formula uses natural, vegetable-based binders and is free from plasticizers, allowing for both dense opaque coverage and delicate watercolor-style washes. The paint dries to a luxurious, velvet-like matte finish that resists cracking, retaining vivid color over time. It is crafted to be lightfast, economical due to its rich pigmentation, and made in Switzerland with precision and consistency—ideal for fine art, illustration, mixed media, and educational use.
