Oil Colour Tube Cobra Artist Water-Mixable Oil Pyrrole Red 315 by Cobra

Cobra Artist Water-Mixable Oil Pyrrole Red 315 is a single-tube water-mixable oil colour formulated for artists seeking the handling and finish of traditional oil paint without the need for solvents. This pyrrole red offers high tinting strength and a vivid, warm red hue that works well in both opaque passages and translucent glazes. The paint can be thinned and cleaned with water, dries to a stable oil-like film, and is suitable for a range of classical and contemporary painting techniques.

Advantages

The formulation provides oil-like consistency and buttery handling while allowing thinning and brush cleaning with water, reducing the use of solvents and odour in the studio. Pyrrole red delivers intense colour saturation and strong covering power, enabling efficient layering, glazing or impasto work. The paint forms a durable film with good adhesion and retains pigment brilliance over time when used according to standard oil-painting practices.

Suitable for

• Fine art painting on primed canvas and panels
• Illustration and colour studies requiring vivid red tones
• Glazing techniques and transparent layering
• Impasto and textured brushwork
• Students and artists preferring low-odour, water-thinnable oils

When it may not be suitable

This water-mixable oil paint is not identical to traditional solvent-based oils in all handling characteristics; some artists may notice slight differences in drying times or brush feel. It is also not intended for use on unprimed or raw wood surfaces without suitable oil-compatible priming, and prolonged exposure to moisture before full curing may affect the paint film.

Key specifications

• Colour family: Warm red (Pyrrole red)
• Paint type: Water-mixable oil colour
• Consistency: Smooth, buttery oil-like paste suitable for brushing and palette knife
• Opacity: High tinting strength with good covering power
• Thinning & cleaning: Water-soluble when wet; no solvents required for thinning or brush cleaning
• Suitable supports: Primed canvas, primed panels and suitable oil-compatible grounds

How to use

Squeeze a small amount from the tube onto the palette. Mix with water sparingly to achieve the desired flow; for more traditional oil behaviour use minimal water or add water-mixable oil medium from the same range. Apply in thin layers for faster drying and stronger adhesion, or use thicker impasto layers where texture is required. Clean brushes and tools with water immediately after use. Allow each layer to dry before applying heavier or more oil-rich layers following the fat-over-lean principle.

What to consider before purchase

• Ensure you will use the paint on properly primed, oil-compatible supports
• Decide if water-mixable oil chemistry matches your preferred drying time and handling
• Consider whether the single pigment’s lightfastness and opacity meet your project needs

Usage recommendations

For layered work, start with leaner mixes (less water or medium) and increase oil content in subsequent layers. Use dedicated water-mixable oil mediums from the same brand to modify flow and gloss while maintaining compatibility. Store the tube capped and in a cool, dry place to preserve pigment performance.
