## Summary description

Cobra Artist water-mixable oil colour in a tube, shade Transparent Oxide Red (378). This oil paint blends with water for easy thinning and brush cleaning while retaining oil-paint handling and drying properties. Suitable for artists working in oils who want solvent-free thinning, glazing, layering and detail work on canvas, panel and primed surfaces.

## Long description

Cobra Artist water-mixable oil colour in Transparent Oxide Red (shade 378) is a professional-grade oil paint formulated to be thinned and cleaned with water while maintaining traditional oil handling and drying characteristics. The tube delivers a buttery, high-opacity pigment mass that permits glazing, layering and fine detail work without the need for solvents. It is formulated for use on canvas, primed panels and other properly prepared surfaces where oil paints are normally applied.
Advantages
This water-mixable oil colour combines the working properties of conventional oils with the practicality of water thinning and brush cleaning. It offers good pigment load and predictable drying behavior, allowing for extended blending time and reliable layering. The formulation reduces the need for turpentine or mineral spirits, which simplifies studio hygiene and ventilation while preserving the depth and richness typical of oil paints.
Suitable for
Artists who want oil-paint handling but prefer solvent-free thinning and cleanup
Glazing, scumbling and layered painting techniques on canvas and primed supports
Detail work and fine brushwork where controlled viscosity is required
Studio use where reduced solvent exposure is desired
When it may not be suitable
If your practice depends on the specific effects produced by traditional solvent-based mediums (for example very rapid thinning with solvents or particular varnishing workflows), this water-mixable formulation may behave differently. For artists who need extremely fast drying times or who rely on solvent-specific mixing properties, adjustments to technique or additional compatible mediums may be necessary.
Key specifications
Colour: Transparent Oxide Red (shade 378)
Paint type: Water-mixable oil colour
Consistency: Smooth, buttery paste suitable for brush and palette knife
Compatibility: Mixable with other water-mixable oil colours and dedicated water-mixable mediums
Suitable surfaces: Primed canvas, primed panels and other oil-accepting grounds
How to use
Apply directly from the tube to your palette. Thin and blend using water or recommended water-mixable mediums to achieve desired viscosity and translucency. For glazing and layering, work with thin, even layers and allow adequate drying time between layers according to environmental conditions. Clean brushes and tools with water and mild soap; for thorough cleaning, use water several times and reshape bristles before drying. Follow standard oil-paint conservation practices when finishing and varnishing; use varnishes compatible with water-mixable oils.
What to consider before purchase
Contains oil-based pigments in a water-mixable vehicle — not the same as acrylic or watercolour
Designed to be mixed with water and water-mixable oil mediums; not recommended to mix with traditional solvent-based oils
Ensure your supports are properly primed for oil paint to prevent absorption or long-term adhesion issues
Usage recommendations
For best results, start with thin layers and build up opacity through glazing or impasto as needed; allow sufficient drying time between layers and use only compatible water-mixable varnishes and mediums to ensure long-term stability.
