Product Features & Technical Specifications

• Classic Ultramarine Pigment: Delivers a deep, saturated blue with a distinctive reddish or violet undertone, historically valued and distinct from other blues like Phthalo or Cobalt.
• Professional Water-Based Acrylic: An artist-quality dispersion paint with a smooth consistency, easy water dilution, rapid drying, and simple cleanup with soap and water.
• Excellent Transparency & Staining Power: A semi-transparent to transparent color with strong tinting strength, ideal for creating deep, luminous glazes and staining mixtures.
• Permanent & Lightfast Finish: Dries to a durable, flexible, waterproof film with high resistance to fading, ensuring the rich blue retains its intensity over time.
• Universal Surface Compatibility: Suitable for all non-greasy, non-water-absorbent surfaces, including primed canvas, wood, paper, and more, with proper preparation.
• Superior Mixing Properties: A primary mixing color for creating a vast range of secondary hues, especially vibrant violets and purples with reds, and deep greens when combined with yellows.
• Convenient 40 ml Metal Tube: Packaged in a sealed, airtight metal tube that protects the paint's quality and allows for precise, controlled dispensing.

Primary Uses & Artistic Benefits

• Deep Skies & Night Scenes: The quintessential color for painting twilight skies, deep azure heavens, and dramatic nocturnal landscapes.
• Rich Shadows & Depth: Perfect for creating clean, transparent cool shadows in portraits, still lifes, and landscapes, adding profound depth without muddiness.
• Essential for Color Mixing:
  • Violets & Purples: Ultramarine + Alizarin Crimson, Quinacridone Red, or Magenta creates a range of rich, clean purples.
  • Deep & Muted Greens: Ultramarine + Yellow Ochre or other earth yellows produces natural, subdued greens (e.g., for foliage shadows).
  • Chromatically Rich Blacks: Ultramarine + Burnt Umber or Burnt Sienna creates a deep, vibrant "colorful black" superior to plain black.
• Glazing & Layering: Its transparency makes it perfect for building depth through multiple glazes, especially over warmer underlayers.
• Historical & Figurative Painting: A traditional color used in classical techniques, ideal for painting rich fabrics, atmospheric depth, and the Virgin Mary's robes in religious art.

Recommended Surfaces & Preparation

• Fine Art Supports: Primed canvas, wood panels, and heavy-weight paper.
• Preparation: For the most vibrant results, apply over a white or light-toned ground. A primer (gesso) is recommended on porous surfaces.

How to Use for Best Results

1. Surface Prep: Ensure your surface is clean, dry, and primed if necessary.
2. Dispensing: Shake tube gently. Squeeze a small amount onto your palette.
3. Application:
   • For transparent glazes: Dilute significantly with water or glazing medium.
   • For more opaque coverage: Use with minimal water or mix with a small amount of white.
4. Key Mixing Ratios:
   • Vibrant Dioxazine-like Purple: Ultramarine + a small amount of Quinacridone Magenta.
   • Warm Black: Ultramarine + Burnt Umber (approx. 1:1 ratio).
   • Shadow Green: Ultramarine + Yellow Ochre.
   • Sky Blue Tints: Ultramarine + Titanium White.
5. Cleaning: Clean brushes and tools immediately with warm, soapy water. Note: Ultramarine can stain bristles slightly over time.

Professional Tips & Comparison

• Vs. Phthalo Blue: Ultramarine is less intensely staining and has a redder bias, making it easier to control and more suitable for naturalistic mixing, especially for skies and shadows.
• Vs. Cobalt Blue: Ultramarine is more transparent and violet, while Cobalt is more opaque and "truer" blue. Ultramarine is generally more economical.
• Creating Depth: For incredible depth in shadows, glaze Ultramarine over a dry layer of Burnt Sienna or other warm earth tone.
• Staining Awareness: While not as extreme as Phthalo, it can stain palettes and brushes. Use a non-porous palette for easy cleanup.
• Storage: Always cap the tube tightly to prevent skin from forming.
