Oil paint tube, Cobra Artist Water-Mixable Oil Colour Phthalo Blue 570, 60 ml

Cobra Artist Water-Mixable Oil Colour Phthalo Blue 570 is a water-mixable oil paint supplied in a 60 ml tube. The formulation allows dilution and cleanup with water while preserving the handling characteristics of traditional oil paints: strong pigmentation, smooth consistency and extended open time for blending and glazing. The colour Phthalo Blue 570 provides an intense, cool blue suitable for a wide range of painting styles from detailed fine art to expressive mixed-media work.

Advantages

This water-mixable oil paint mixes easily with water without the need for solvents, reducing odour and simplifying studio cleanup. It retains the sheen, drying profile and blending behaviour associated with conventional oil colours, enabling glazing and layered techniques. The 60 ml tube is convenient for both studio use and portable painting, and the concentrated pigment load ensures good coverage and colour intensity.

Suitable for

• Fine art oil painting and portraiture
• Glazing and layered techniques
• Mixed-media projects where reduced solvent use is preferred
• Art students and professional artists seeking solvent-free cleanup
• Plein air painting with minimal equipment

When it may not be suitable

Artists who require the exact solvent behaviour of traditional oil paints for certain mediums or varnishes may find water-mixable oils behave slightly differently in very specific processes. Heavy impasto techniques that rely on coarse texture pastes or very slow drying layers should be tested, as drying times and surface characteristics can vary compared with conventional oils.

Key specifications

• Type: water-mixable oil colour
• Colour: Phthalo Blue (cool, intense blue)
• Volume: 60 ml tube
• Handling: smooth consistency with extended open time for blending
• Cleanup: water-dilutable and water-cleanable without solvents
• Application: suitable for glazing, layering and mixed media

How to use

Use Cobra Phthalo Blue straight from the tube or dilute gradually with water to achieve lighter tints. For mixing with other colours, combine on a palette using a palette knife or brush; the paint blends similarly to traditional oils. Clean brushes and tools with water and mild soap immediately after use. When working in layers, allow adequate drying time between layers to avoid surface tackiness; drying time depends on film thickness, ambient temperature and ventilation.

What to consider before purchase

• Confirm that a water-mixable oil formulation meets your medium and varnishing workflow
• Test compatibility with any additives, mediums or varnishes you plan to use
• Consider tube size (60 ml) relative to expected consumption and storage
• Note that drying time varies with film thickness and environmental conditions

Usage recommendations

For best results, begin with thin layers and increase paint thickness progressively. Use dedicated water-mixable oil mediums from the same brand to maintain consistent drying and finish, and allow full curing before applying traditional varnishes if used.
