colorimetry. The three additive primary colours are red, green, and blue; this means that, by additively mixing the colours red, green, and blue in varying amounts, almost all other colours can be produced, and, when the three primaries are added together in equal amounts, white is produced.
What is yellow ochre used for?
In contemporary times, ochre remains an important material. It is still used as a dye, but has found other applications such as in catalysis, as a cement additive and in the synthesis of iron nanoparticles. This is in addition to its use as an ore of iron; limonite can contain up to 59.8% iron(3).
