Iron oxide yellow
Iron oxide yellow is a pigment that gives earthy yellow colours. It is lightfast and has a high degree of opacity. It is used for both interior and exterior painting with linseed oil.
Nowadays iron oxide pigments are produced synthetically. They are lightfast and permanent, with a high opacity and tinting strength. The colour of the iron oxide pigments vary depending on the chemical compound of iron and oxygen. The chemical composition of iron oxide yellow is similar to that of the yellow ochres (yellow ochre and gold ochre), but creates stronger and brighter colours.
Kulturkulör’s mixing chart describes how you can mix traditional linseed oil paints to achieve specific colours. The chart shows the result of mixing ready-made paints and the parts are stated in percent by weight.
NCS – Natural Colour System®© is a logical colour system which builds on how the human being sees colour. The NCS notation makes it possible to describe the colours of all surface materials. You can read more about the NCS system here.
There are mixing charts for a selection of the colour samples in Kulturkulör. In the sample collection you can find more nuances that you can create with linseed oil paint and traditional pigments. The mixing charts will give you an idea of how the colour changes when mixing with white and in some cases when adding black. The mixing ratios are approximate and the properties of the pigments vary.
The mixing chart is colour coded to give an idea of the result of the mixture and what colours you can achieve with the traditional pigment, but keep in mind that the colour display varies between computer screens.
