It produces a deep, warm red with a brick\u003cspan\u003e-\u003c\/span\u003ecrimson undertone and a richly saturated masstone. Compared to iron oxide reds, Copper Red is generally slightly cooler and less earthy, with a subtle metallic\u003cspan\u003e-\u003c\/span\u003emineral character; compared to modern organic reds, it is more muted and natural, better suited to historical and atmospheric color work than to high-chroma, synthetic effects.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn use, Copper Red gives a powerful yet controlled red ideal for brickwork, rooftops, terracotta, rust, autumn foliage, textiles, and warm shadows in landscape and figurative painting. It has strong tinting strength and a semi-opaque character, allowing it to cover well in masstone while still producing luminous, warm glazes in thinner applications. It mixes beautifully with yellows and earths for a wide range of tile, brick, and terracotta hues, with blues and blue-greens for complex, near-black neutrals and shadow colors, and with violets and magentas for deep wine reds and muted maroons that remain clear rather than muddy.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThis copper oxide pigment is chemically stable, heat-resistant, and highly resistant to acids and alkalis, which makes it suitable across a wide range of binders and mediums. In artist\u003cspan\u003e'\u003c\/span\u003es colors it offers a robust, mineral red that can function as a primary earth-adjacent red on the palette, an alternative to iron oxide reds, or a key mixer for historical, architectural, and industrial subjects where a convincing, slightly metallic red is desirable.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eCopper compounds have been used as colorants since antiquity, from Egyptian and Mediterranean cosmetics and ceramics to Roman architectural finishes and medieval glass.

These same copper oxide reds were later adapted for artist materials, offering a dense, warm red that bridges the gap between traditional earth reds and more saturated modern organics. Today, Copper Red remains a specialty pigment, appreciated by painters and ceramicists who want a durable, mineral red with a distinct, slightly metallic warmth and a strong historical lineage.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Synthetic (Inorganic) copper oxide red pigment (cuprous oxide)\u003c\/p\u003e\u003cp\u003eSuitable Mediums: Watercolor, Oil, Tempera, Acrylic, Encaustic, Cold Wax, Casein, Milk, Swedish Flour, Lime \/ Fresco, Ceramics\u003c\/p\u003e\u003cp\u003eLightfastness: Best\u003c\/p\u003e\u003cp\u003eOpacity: Opaque\u003c\/p\u003e\u003cp\u003eOther Names: Copper Red, Copper Oxide Red, Cuprous Oxide Red\u003c\/p\u003e\u003cp\u003eColor Index Code: Copper oxide\u003cspan\u003e-\u003c\/span\u003ebased red pigment\u003c\/p\u003e","brand":"Morrow Archival","offers":[{"title":"2 Grams","offer_id":47875251405022,"sku":"PS-682-0000-0002g","price":16.0,"currency_code":"USD","in_stock":true},{"title":"10 Grams","offer_id":47875251437790,"sku":"PS-682-0000-0010g","price":32.0,"currency_code":"USD","in_stock":true},{"title":"20 Grams","offer_id":47875251470558,"sku":"PS-682-0000-0020g","price":48.0,"currency_code":"USD","in_stock":true},{"title":"50 Grams","offer_id":47875251503326,"sku":"PS-682-0000-0050g","price":96.0,"currency_code":"USD","in_stock":true},{"title":"100 Grams","offer_id":47875251536094,"sku":"PS-682-0000-0100g","price":174.0,"currency_code":"USD","in_stock":true},{"title":"500 Grams","offer_id":47875251568862,"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\/c83555a9-0f79-4d0a-af6a-7c4605c3a23b-copy.jpg?v=1769982691","url":"https:\/\/morrowarchival.com\/products\/copper-red-pigment-425137809","provider":"Morrow Archival","version":"1.0","type":"link"}
