 Morning class, this is Wilkamp from Wilkamp Art School and this is a quick demo on mixing cad yellow light and purple to show you the complementary colors. You don't use these colors as often as you might use a blue and orange which you can use in a great deal of paintings, but sometimes the color you're after is this mixture between the yellow and the purple. I often find using the yellow and the purple is handy in portraits especially when I'm getting near the end of a portrait. If I'm using say an Indian red and ultramarine blue and then add a little bit of a yellow ochre to it I can often get the perfect tone that I'm after. This is with an illiterate crimson and ultramarine blue again with a cadmium yellow light. Often when you're first starting to paint a good way to understand pigments and how they work you have to use a separate red and a separate blue to mix your purples rather than relying on a premixed purple. This way you will learn to judge which pigments to choose depending on what results you want. So sometimes I want quite a dull purple so I'll use a cadmium red and ultramarine blue because I know that this will create quite a muted effect which will be very nice for say mountains in the distance of a landscape painting.
