Colour pigments are integral to our lives. They are all around us. Coming to paintings and artworks there are so many colour mediums available these days-- Water colours, Oil colours, Acrylic colours ,
Wax crayons, Pencil colours, Pastels, Pens, .....the list is endless..
Understanding of mediums, how they are made, how they behave on different base helps an artist a lot. There was a time when artists used to make colours on their own , but with technological and scientific advancements we have the luxury of ready to use colours.
OIL COLOURS ; The colour pigments are same in all. How they are bound gives them the body and types. In oil colours as the name explains itself , pigments are bound in oils and contains fillers. The fillers are used to give body to colours. There are two types of oil paints-- artist quality and less expensive ones for students . The artist quality ones use best oils and pigments and contain more quantities of fillers. Normally filler consists of aluminium hydrate or blanc fixe. The fillers are white pigments which are used to give body to paints. The oils commonly used to bind the pigments are linseed oil, poppy oil, sunflower oils....
The colour pigments are derived both from natural and artificial sources. Oil colours are available in tubes, tubs and bars. These days water mixable oil paints are also available for people who are allergic to oils and solvents used in traditional oil paints .In oil colours the drying time is long, which gives us enough time to correct our mistakes. The oil colours are very smooth and creamy. They can be used directly from the tube , can be thickened by adding additives and can be thinned by using thinners and various oils . Linseed oil , turpentine oils are commonly used to thin the oil colours. For people who are allergic or can't stand the odour of spirits and turpentine oil , low odour thinners are also available.
In India Camlin is one of the most commonly used brand, but these days many international brands like Pebeo , Daler - Rowney and so many others are also available.
