Spotlight on Colour: Indian Red
It is the iron oxide in the ground which creates the red colour. Unlike Yellow and Brown earth colours, Indian Red does not contain water in its chemical structure, which creates the deep red colour. Earth colours were among the most permanent pigments throughout the 15th – 18th century so artists relied heavily on them, notably in Old Master oil paintings. The pigmented earth was dug up in sticks and used as makeshift crayons for drawing by artists such as Rembrandt and Michelangelo.
In the 18th century, Indian Red became a synthetic pigment, also known as Mars Violet, though the latter is a slightly more subdued pigment. This allowed a more consistent colour to be available for painters rather than the variable pigment created from different soils. Indian Red pigment has a blue undertone, while its yellow counterparts are known as English or Venetian Red.
A reliable and essential colour for any water-colourist or oil painter, Indian red can be used for landscapes and portraiture alike. It is generally considered a standard pigment of a painter’s palette. Its opacity allows the painting of smooth flat surfaces showing little brushstroke as well as covering previous colours or washes. It has strong tinting powers and when mixed with other colours it creates cool mixes.
