Painter and teacher Richard Robinson has created a free interactive tool that lets you experiment with gamut masks.
With the digital interface, you can choose from a set of pre-shaped gamuts and move them around on either a traditional or a Yurmby wheel. Or you can draw your own gamut shape. The sliders let you shift the value or neutralize the chroma of the wheel in increments.
Once you find a gamut or a range of colors that you like, you can mix color strings and paint from them. The gamut-mapping method will be part of my new book on color and light coming out in the fall.
