Decor colors has a wide selection of color pigments in different tones, they can be ordered here online in our web shop, or buy directly in our store at Nørreport. If you want more information and knowledge about color pigments and their properties. I can recommend looking at our blog, under non-fiction. Here are a few books that might be of interest. In particular, I would recommend the book Chromatopia.
Pigment
Decorfarver sells pigments, which can be used for the manufacture or toning of various types of paint, eg lime, tempera or linseed oil paint or dyeing of mortar or plaster. The classic color scale consists of the earth colors as well as chromium oxide green, ultramarine and Prussian blue. These colors are mutually harmonious and complement each other well. Just think, for example, of the old whitewashed facades in Nyhavn.
Inorganic pigments
Are the so-called naturally occurring earth tones that have been known since the dawn of time. They are usually loose stones or soils that do not need much processing before use. Most earth colors contain alkaline iron compounds and can therefore change the color shade from eg yellowish to a more reddish tone when annealing (burning). During annealing, the iron compounds in the pigment are oxygenated, hence the name iron oxides, which are used for many of the reddish pigments. The inorganic colors are generally far more durable against the light and less influenced by the air, than the organic pigments. They are the most lightfast pigments that exist and can keep their hue for centuries. They have an excellent mixing ability in most known binders. Some of the inorganic pigments are today synthetically produced.
Organic pigments
Are called the colors that have either animal or vegetable origin, eg plant colors. However, the vast majority of organic pigments are chemically produced. Most modern synthetic organic pigments are clearer, stronger in colour. There can be big differences between them, both in terms of lightfastness and recommended use. They are generally much less weather resistant than the inorganic pigments.
