Oil Painting Tip Of The Week (27th March 2005)
Oil paints are generally available in two grades:
'Artist' (the best quality) and 'Student' (for beginners or sketching)
'Artist' quality paints are by far the best and offer a large range of colours. They have a high concentration of pigment which is very finely ground.
'Student' quality paints are much cheaper and the range of colours more limited. Some of the more expensive pigments are replaced by cheaper substitutes. They may also have a lower concentration of pigment and contain fillers, which in some case can reduce colour strength.
My advice would be to always buy the best you can afford.
