Oil colour tube Cobra Artist Water‑Mixable Ultramarine 40 ml (ROY-21055040)

Cobra Artist Water‑Mixable Ultramarine 40 ml is a water‑compatible oil colour formulated for artists who prefer traditional oil painting techniques without the need for solvents. The paint comes in a 40 ml tube and delivers a deep ultramarine hue with high tinting strength and buttery working properties. Designed to be thinned and cleaned with water, this oil colour adapts to studio practice, plein air painting and mixed‑media workflows while maintaining the handling characteristics of conventional oils.

Advantages

This water‑mixable oil colour provides strong pigmentation and a smooth, controllable consistency that responds well to glazing, blending and impasto. Its water compatibility reduces the need for turpentine or mineral spirits for thinning and cleanup, making it suitable for use in shared or domestic spaces. The formulation retains traditional oil drying behaviour and film properties while offering easier cleanup and simpler thinning with water or water‑based mediums.

Suitable for

• Canvas and prepared boards
• Studio painting and plein air work
• Glazing, glazing blends and layered oil techniques
• Mixed‑media projects where water compatibility is required

Key specifications

• Colour: Ultramarine
• Volume: 40 ml
• Type: Water‑mixable oil colour

How to use

Squeeze a small amount of paint onto the palette and mix with water or a recommended water‑mixable medium to achieve the desired consistency. Apply in thin to medium layers for faster drying or thicker layers for impasto effects, allowing adequate drying time between layers. Clean brushes and tools with water immediately after use. When extending working time or increasing gloss, use only water‑mixable mediums formulated for this paint to maintain film integrity.

Usage recommendations

Use ground and properly primed supports to ensure long‑term adhesion and stability. Allow sufficient drying time between layers and avoid mixing conventional solvent‑based oils with water‑mixable oils to prevent incompatibility in the paint film.
