Viridian Hue is the cool, blue-biased chromatic green for ocean water, coastal subjects, and the blue-green end of the colour spectrum. Where Sap Green is warm and naturalistic for foliage, Viridian Hue sits distinctly cooler: a clear, transparent blue-green that accurately captures the colour of shallow tropical water over sand, glass-like wave faces, and the deep teal tones of open water in strong sun. Art Spectrum Studio Blend Oil Viridian Hue uses a phthalocyanine-based formulation that matches the colour and optical qualities of the original Viridian (PG18) pigment, delivering the same cool, transparent blue-green with excellent lightfastness and the broad compatibility of synthetic phthalocyanine chemistry.

What Makes This Colour Special

The defining colour character of Viridian Hue is its coolness: it sits distinctly on the blue side of the green spectrum, which is why it describes ocean and coastal water more accurately than the warmer, more yellow-green Sap Green. Most tropical and subtropical ocean water, when viewed without the influence of the sky reflection, reads as a blue-green in the Viridian register, particularly in the shallow areas where the sandy or coral bottom is visible through the water column. The transparency of the paint is essential to capturing this effect: a transparent Viridian Hue glaze over a pale ground allows the lighter tone of the bottom to show through, simulating the way shallow clear water looks from above.

The complementary relationship between Viridian Hue and the warm red-orange earth colours is the most important mixing dynamic for Australian coastal subjects. Red-orange (such as Burnt Sienna or Cadmium Red Hue) is the direct complement of blue-green (Viridian Hue), meaning the two colours neutralise each other toward grey when mixed in equal amounts, and vibrate strongly as complements when placed next to each other on the canvas. For coastal rock and beach scenes, the contrast between the orange-red of wet sandstone, iron-stained rock, or rusted surfaces against the blue-green of adjacent water is a classically Australian coastal colour relationship that is most accurately mixed using Viridian Hue and the relevant warm earth or red colour in concert.

Why Art Spectrum Studio Blend Oil Belongs on Your Palette

• The essential Australian tropical water colour. The luminous blue-green of Whitsundays, Great Barrier Reef, and Queensland coastal water is Viridian Hue territory. No other single colour captures the clear, tropical ocean blue-green more directly.
• Transparent for luminous water glazing. The transparency of Viridian Hue is the key to painting the see-through quality of shallow tropical water. Glazed over a pale ground, it gives the luminous, sand-visible-below quality that makes tropical water look tropical.
• ASTM I lightfastness. Phthalocyanine pigments are among the most stable synthetic organics. Viridian Hue will not fade or shift under any normal conditions.
• Distinct from Sap Green. Viridian Hue is cool and blue-biased; Sap Green is warm and yellow-biased. The two greens serve entirely different subjects: Viridian for water and complementary contrast in coastal paintings; Sap Green for foliage and naturalistic vegetation. Both have a place on the palette.
• Australian-made since 1966. Art Spectrum has produced artists' materials from their Epping, Victoria facility for over six decades.

Getting the Most Out of This Tube

For painting tropical and subtropical water, begin by laying in the pale underpaint that represents the sandy or coral bottom in very shallow areas. A mixture of Titanium White with a small amount of Yellow Ochre or Raw Sienna gives the pale, warm tone of sand seen through clear water. Allow this to dry, then glaze thinned Viridian Hue over the dry underpaint, allowing the pale layer to show through. The depth of the glaze controls the apparent depth of the water: a very thin glaze gives very shallow, almost transparent water; a heavier glaze gives the stronger blue-green of chest-deep tropical water. For the open water beyond the shallow zone, mix Viridian Hue with Phthalo Blue and a touch of Titanium White to give the richer, darker teal-blue of open ocean.

For the breaking, foaming edges of waves and surf, mix Viridian Hue with Titanium White and a trace of Phthalo Blue to give the clean, intense blue-green of the transparent face of a wave just before it breaks, where the sunlight passes through the thin water and the colour is at its most saturated and brilliant. This is a colour unique to surfing beaches in strong sunlight, and Viridian Hue is the basis of the mix. The foam itself, where the water is aerated and white, uses Titanium White modified with a very small amount of Viridian Hue to keep the foam reading as slightly cool rather than a flat, warm white.

For coastal scenes dominated by warm ochre, sandstone, and rust-coloured subjects, Viridian Hue mixed in small quantities into the dark shadow areas will introduce a cool, complementary note that increases the visual impact of the warm subject colours. The eye reads the warm-cool contrast as increased vibrancy in both colours, making the ochre sand appear warmer and the Viridian shadow appear more richly blue-green. This technique of using small amounts of the complement in shadow areas is one of the fundamental colour tools of coastal painting.
