Ecoline Liquid Watercolour Cardboard Set is a transparent dye-based liquid watercolour set designed for illustration, design, calligraphy, and expressive painting techniques. The colours are highly luminous and intensely vibrant, allowing smooth dilution with water for lighter tones and seamless blending for gradients and layered effects.

The ink remains reactivatable when dry, enabling reworking and continued manipulation of washes for fluid artistic applications on paper, illustration board, and cardboard surfaces.

This set includes Lemon Yellow (205), Vermilion (311), Magenta (337), Ultramarine Deep (506), Sky Blue (578), Green (600), Burnt Sienna (411), and Black (700).
