These colours put a smile of my face unlike this depressing grey sky outside my studio...So i've made a little selection from my Pinterest Colour Board for you to keep on smiling :-)
Left: Color Wheel by Moses Harris, (1766). Moses Harris's chart was the first full-color circle. The 18 colors of his wheel were derived from what he then called the three 'primitive' colors: red, yellow and blue. At the center of the wheel, Harris showed that black is formed by the superimposition of these colors.
