Saturated Colour
A colour applied to give optimum brightness and richness.
A broken layer of (usually) lighter, opaque colour scrubbed dryly over a darker under-colour.
Greens, oranges and purples, produced by combinations of the primary colours, red, yellow and blue.
These are not quite complementaries. For example, the true complementary of blue is orange, so a warm yellow would be its split complementary.
An artists’ colour that is made to sell at an economical price. This will often mean using either second grade binders and “hue” pigments or using extenders to reduce the pigment content. Some of the substitute pigments may have reduced lightfastness. Student colours are designed for beginners and, of course, students, although some “professionals” use them.
