To us this is possibly better described as a dark yellow ochre, exhibiting very similar characteristics to that hue, however there is no denying from the tube it is brown.
Hydrated iron oxide is the principle colouring agent in ochres. This colour is based on the natural mineral goethite associated with varying proportions of other minerals, such as clay, chalk and silica. They differ from other red ochers in that they contain water. In other words, the iron to which they owe their color is hydrated iron oxide. Natural ochres are absolutely permanent and have good covering power.
Rublev Italian Brown Ochre is a semi-transparent brown with good tinting strength, medium grained that makes yellow biege half tints. This natural earth is from quarries in northern Italy
