The Couture Creations Alcohol Ink Cerulean is a clean blue alcohol ink, perfect for creating airy backgrounds, water effects, skies and fluid colour gradients. It works beautifully on non-porous surfaces such as Yupo, glossy paper, glass, metal and plastic, flowing smoothly and drying quickly. Use it on its own for a bright, clear result or combine it with deeper blues, turquoise and metallic inks for effects with depth, transparency and movement.
