DANIEL SMITH Luminescent Watercolour Paint Tube — Interference Lilac 15ml, Iridescent Sheen

DANIEL SMITH Luminescent™ Watercolour in Interference Lilac is a 15ml tube of iridescent watercolour pigment designed to add pearlescent, colour-shifting sheen to paintings.

This Interference Lilac is part of DANIEL SMITH’s Luminescent line — specialty watercolours formulated for optical effects like shimmer, sheen and subtle colour shifts that appear when light hits the paint. Housed in a 15ml tube, the pigment is mixed with pure gum arabic and milled to produce a consistent, usable texture for washes, glazes and detailed work. Like all DANIEL SMITH watercolours, it’s produced in Seattle and formulated for high pigment load and dependable handling.

How does Interference Lilac change the look of my watercolour pieces?

Interference Lilac reflects light and alters apparent colour depending on viewing angle and underlying layers, creating luminous highlights and iridescent accents. It’s ideal for rendering metallic sheens, glints on feathers, or subtle pearly transitions in backgrounds.

• Adds an iridescent sheen that shifts between lilac and silvery tones.
• Works over dark and light layers to produce different visual effects.
• Best used in glazes or diluted washes to preserve luminosity.

What are the working properties and recommended techniques?

This Luminescent paint behaves like a fine watercolour but carries light-reflective particles that show best in thin, even layers or sparing highlights. It reactivates with water like standard watercolours, so you can lift or blend, but layering will change the sheen.

• Apply as a transparent glaze for subtle iridescence.
• Use sparingly for accents; heavier application increases opacity of effect.
• Mixes with other DANIEL SMITH colours to create custom luminescent blends.

How permanent and stable is the colour?

DANIEL SMITH Luminescent paints are manufactured to meet high industry standards for permanence and quality control; batches are tested for performance. While specialty effects rely on interference pigments rather than traditional cadmium, the product aims to deliver reliable lightfastness and consistent handling.

• Formulated with pure gum arabic and high pigment load for longevity.
• ASTM-rated excellent lightfastness for this product line.
• Non-staining and transparent, preserving layering and lifts.

How should I care for paintings made with Luminescent Interference Lilac?

Handle finished pieces like other watercolours: mount behind glass if possible to minimize abrasion and UV exposure; avoid harsh cleaning. For best archival results, keep artworks out of direct sunlight and use acid-free matting and backing.

• Frame under UV-filtering glass to protect sheen and colour.
• Store flat in a dry, cool environment away from direct light.
• Avoid heavy varnishes that might obscure the iridescent effect.

Who is this for: Artists who want to introduce luminous, shifting highlights into their watercolours—illustrators, botanical painters, wildlife artists, and mixed-media creators will appreciate Interference Lilac for accents, glazes and special-effect areas. Beginners curious about optical effects can experiment using DOT Cards or small mixes, while experienced painters will find precise control from the 15ml tube format for studio projects or commissions.
