The palette of oil painting is very important.Many impressionists did not use black. That makes sense because they were keen to find colour and light in everything, even the darkest shadows.
The old masters, however, used black extensively, keen as they were on dramatic lighting (chiaroscuro). In general most artists’ palettes contain the primary colours (red, blue, yellow), white, black and brown. It is usual to have a warm and a cool version of each colour, so for example a warm yellow ochre and a cool lemon yellow. Some artists have become famous for a limited palette. Anders Zorn, for example, famously only used yellow, red, black an white. This is a great palette for portrait work.
Here are some oil paintings worthy of appreciation.I hope you found this blog post interesting.
