DANIEL SMITH Extra Fine Watercolour Paint — Interference Green 15ml, Iridescent Shimmer Glaze

Daniel Smith Extra Fine Watercolour — Interference Green is a 15ml professional watercolour tube that offers a shimmering, iridescent green designed to add luminous sheen and subtle colour shifts to your paintings.

This Interference Green comes from DANIEL SMITH’s Extra Fine line, formulated for artists who want long-lasting pigments, clean mixing behavior, and special optical effects. Made in Seattle with high-quality pigments and pure gum arabic binder, the colour is engineered for permanence and smooth handling while producing a pearlescent surface when applied thinly or glazed over darker washes.

What makes Interference Green different from ordinary greens?

Interference Green is a luminescent pigment that creates iridescence by reflecting light differently than traditional pigments. Instead of relying solely on colour opacity, it produces a shifting sheen that can read metallic or pearly depending on viewing angle and the ground beneath it. It’s excellent for adding reflective highlights or subtle shifts in foliage, feathers, and other surfaces where light plays a role.

• Luminescent optical effect for shimmer and depth
• Best used over dark or contrasting layers to reveal the interference sheen
• Transparent and non-opaque — layers influence final appearance
• Designed for reliable lightfastness and durability

How does it behave when mixed or layered with other colours?

Interference Green is a transparent, non-staining pigment that tends to keep its optical effect when glazed over other colours, but mixing with heavy opaques will mute the sheen. For the brightest iridescence, apply thin glazes or overlay on darker tones. In mixtures, it can subtly shift hue without overpowering the partner pigment.

• Works best as a glaze or top layer to preserve sheen
• Mix sparingly with other colours to retain interference properties
• Combines well with granulating pigments for textured highlights
• Non-staining, so lifting and reworking are manageable

What surfaces and techniques highlight its special effects?

Use Interference Green on cold-pressed or smooth hot-pressed paper to control how light interacts with the pigment. It excels in washes, glazes, and delicate dry-brush applications for sparkles of sheen. Combining it with DANIEL SMITH’s PrimaTek or granulating colours produces striking contrasts between matte texture and luminous accents.

• Glazes over dark washes reveal strongest iridescence
• Dry brushing adds pinpoint highlights and shimmer
• Works on watercolour ground for non-paper surfaces
• Pairs well with granulating colours for natural textures

Who is this for? Interference Green in a 15ml tube is made for painters who want to expand their palette with special-effect pigments—illustrators, botanical and wildlife artists, mixed-media creators, and professionals seeking archival-quality materials. Beginners curious about optical effects will appreciate the forgiving transparency and ease of glazing, while experienced artists will value the unique reflective qualities DANIEL SMITH is known for.
