NATURAL OXIDES: yellow, red, brown, black STAIN, COLOURED STAIN SYNTHETIC IRON OXIDES: yellow, red, brown, black CHROME OXIDE GREEN COBALT OXIDE: green, blue ULTRAMARINE: blue, violet CARBON- or PITCH-BLACK TITANIUMDIOXIDE WHITE LEAD CHROMATE : yellow, orange WATER-SOLUBLE DYES: acid and basic A dye is a substance that needs a certain affinity with the carrier on which it is being applied. Hence a bond is created and the colouring capacity emerges. Contrary to a pigment, a dye is a dissolvable colorant and the colouring capacity will only show when dissolved. Dyes always have an organic compound. For more than 5000 years, natural resources have been the base for dyes. Leafs, roots and berries are just some of the components. Nowadays, most of these components have been replaced by synthetic variants. Of course, special dyes are applied when considering nutrition.

Liquid and powdered fertilizers, sowing seed NATURAL OXIDES: yellow, red, brown, black BISTER SYNTHETIC IRON OXIDES: yellow, red, brown, black DRAGON PIGMENTS: red, yellow, blue, green, grey A pigment is a substance that has the capacity of colouring a certain carrier (cement, plaster, synthetic fibres, paint, …). Contrary to dyes, pigments are insoluble. Therefore, pigments remain under the form of small particles and will just be dispersed in the carrier and so colouring the carrier. The colouring capacity of the pigment depends on the fineness of the particles composing the pigment. In general we can say that the finer the particles are, the higher the colouring capacity of the pigment will be. A pigment is only suitable for certain applications. The pigment shouldn’t react with the carrier. Moreover, the pigment shouldn’t oxidize under influence of oxygen in the air and shouldn’t lose its colour under influence of sunlight (UV).
