It produces a rich, warm yellow that leans toward yellow-orange, with a glowing, egg yolk or cadmium-deep character in masstone and a clear, luminous quality in washes. Compared to traditional cadmium and azo yellows, this pigment is more transparent and cleaner in mixtures, offering a high-chroma warm yellow that still feels natural and versatile rather than harsh.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn use, Isodoline Yellow gives a brilliant, transparent to semi-transparent yellow ideal for sunlight, autumn light, florals, foliage highlights, golden textiles, and warm glazes in both landscape and figurative work. It has good tinting strength with a smooth, non-granulating character, making it excellent for glazing, layered washes, and precise color mixing. It combines beautifully with blues for a range of vibrant, slightly muted natural greens, with reds and magentas for deep oranges and fiery scarlets, and with earth pigments to create clear, sunlit ochres and golden browns that stay bright rather than muddy.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThis isoindoline pigment is highly lightfast, chemically stable, and compatible with a wide range of binders and mediums. In artist\u003cspan\u003e'\u003c\/span\u003es colors it serves as an outstanding warm primary yellow for modern mixing palettes, providing both a glowing statement color and a reliable mixer for clean greens, oranges, and warm, luminous neutrals.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eIsoindoline and related isoindolinone yellows were developed in the mid-20th century as part of a new generation of high-performance organic pigments engineered for industrial coatings, plastics, and printing inks. They were designed to offer excellent lightfastness, weather resistance, and chemical durability\u003cspan\u003e, \u003c\/span\u003equalities that quickly attracted the attention of artists and paintmakers looking for modern alternatives to more fugitive azo yellows and traditional lake colors.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIsodoline Yellow (PY139) represents a warm, orange-leaning member of this family, sitting between traditional gamboge-style yellows and deeper cadmium yellows in hue. Its combination of strong chroma, transparency, and permanence led to its adoption in professional artist ranges, where it often appears as a replacement or complement to cadmium yellow deep in watercolor, oil, and acrylic. Today it is valued by painters who want a dependable, lightfast warm yellow that remains clear and luminous in both masstone and glaze, and that harmonizes easily with both modern and historical palettes.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Synthetic (Organic) isoindoline yellow pigment\u003c\/p\u003e\u003cp\u003eSuitable Mediums: Watercolor, Oil, Tempera, Acrylic, Encaustic, Cold Wax, Casein, Milk, Swedish Flour, Lime \/ Fresco\u003c\/p\u003e\u003cp\u003eLightfastness: Best\u003c\/p\u003e\u003cp\u003eOpacity: Transparent to semi-transparent\u003c\/p\u003e\u003cp\u003eOther Names: Isodoline Yellow, Isoindoline Yellow, Pigment Yellow 139\u003c\/p\u003e\u003cp\u003eColor Index Code: PY139\u003c\/p\u003e","brand":"Morrow Archival","offers":[{"title":"2 Grams","offer_id":47875254649054,"sku":"PS-657-0000-0002g","price":16.0,"currency_code":"USD","in_stock":true},{"title":"10 Grams","offer_id":47875254681822,"sku":"PS-657-0000-0010g","price":32.0,"currency_code":"USD","in_stock":true},{"title":"20 Grams","offer_id":47875254714590,"sku":"PS-657-0000-0020g","price":48.0,"currency_code":"USD","in_stock":true},{"title":"50 Grams","offer_id":47875254747358,"sku":"PS-657-0000-0050g","price":96.0,"currency_code":"USD","in_stock":true},{"title":"100 Grams","offer_id":47875254780126,"sku":"PS-657-0000-0100g","price":174.0,"currency_code":"USD","in_stock":true},{"title":"500 Grams","offer_id":47875254812894,"sku":"PS-642-0000-0500g","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2821\/2702\/files\/d4f41cb8-99e0-44ac-a68b-6ede61f5ad10-copy.jpg?v=1769982692","url":"https:\/\/morrowarchival.com\/products\/isodoline-yellow-pigment-425137815","provider":"Morrow Archival","version":"1.0","type":"link"}
