This variation of the classic ultramarine blue brings a cooler, more intense colour to the palette, making it perfect for capturing clear skies, ocean depths, and lush landscapes. Its vibrant yet natural tone offers a sense of clarity and brightness, ideal for creating crisp, fresh compositions with a touch of atmospheric depth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltramarine Blue (Green Shade)\u003c\/strong\u003e is semi-opaque, providing smooth, even washes with excellent layering potential. When applied at full strength, it delivers a deep, rich blue, and when diluted, it softens into lighter, cooler blues—perfect for rendering skies, water reflections, or soft backgrounds. This pigment also features slight granulation, adding texture and complexity to washes, giving depth and dimension to painted areas.\u003c\/p\u003e\n\u003cp\u003eKnown for its excellent lightfastness, \u003cstrong\u003eUltramarine Blue (Green Shade)\u003c\/strong\u003e maintains its cool, vibrant tones over time. It mixes well with other pigments, creating clean greens when combined with yellows or deepened shadows when mixed with darker blues and earth tones. This versatile pigment is a favourite among artists for its ability to add bold, cool blues to landscapes, seascapes, and abstract works, while also offering the flexibility for subtle blending and tonal variation.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.jackmansartmaterials.co.uk\/blogs\/news\/ultramarine-pigments-in-depth\" title=\"Learn more about Ultramarine Pigments in Depth\" rel=\"noopener noreferrer\" target=\"_blank\"\u003e Learn more about Ultramarine Pigments in Depth \u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eWe Recommend\u003c\/h2\u003e\n\u003cp\u003eUsing \u003ca href=\"https:\/\/www.jackmansartmaterials.co.uk\/products\/distilled-water\" title=\"Use distilled water with handmade watercolours\" rel=\"noopener noreferrer\"\u003edistilled water\u003c\/a\u003e with all our watercolours to keep each pigment at its purest form.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeel free to message us with any questions – we’re happy to help!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOur watercolours are perfect for artists of all skill levels, from beginners to advanced, who value high-quality, professional-grade materials.\u003c\/p\u003e\n\u003ch2\u003eProduct Information\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003ePigment\u003c\/strong\u003e\u003c\/th\u003e\n\u003ctd\u003ePolysulfide of sodium sulfo-aluminate of silicon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003ePigment C.I.
