Golden High Flow Acrylics 30ml - S4 - Phthalo Blue (Green Shade) is a professional ultra-fluid acrylic paint with an ink-like consistency, designed for artists who want strong colour, smooth flow and excellent control. This Series 4 colour is made with pigment PB15:3 and has a semi-transparent finish with excellent lightfastness, making it a dependable choice for archival work, glazing and high-intensity colour mixing. GOLDEN describes it as the greenish variation of this powerful, versatile blue, noting that it appears dark and more opaque in heavier applications while extending beautifully into transparent glazes.

Its vivid blue character and strong tinting behaviour make it especially useful for airbrush work, illustration, botanical painting, seascapes, contemporary landscape painting and mixed media techniques. This colour is ideal for glazing, colour washes, staining, layered transparent passages and expressive mark-making where a clean, high-chroma blue is needed.

Like the rest of the High Flow range, it can be used straight from the bottle in an airbrush, refillable marker, dip pen, technical pen or brush. Its very thin consistency gives artists the handling of an acrylic ink with the permanence of professional acrylic paint, while remaining compatible with other acrylic colours and mediums.
