Pigments
Pigment is a colouring substance which can be used in the manufacturing of paint.
It is usually ground into powder and then mixed with water,
oil, or another base to produce artist paint and similar products.
To avoid many of the chemical substances from ready-made pant tubes,
many artists choose to create their own paint by mixing pigments with a base substance.
For example oli paint can be made by mixing coloured powder (pigment) with linsead oil.
In order to make acrylic paint you need to mix the pigments with water and acrylic polymer emulsion
(which is the binder in acrylics.)
As acrylics dry very fast it is important to remember that unlike oil, the available mixing time is very short.
Watercolours and Gouache are pigments mixed with Gum Arabic, which is also used as a watercolour medium
to increase drying time and add more transparency.
