I've worked with a lot of designers in my life (due to my work in Marketing) so I'm well aware of CMYK. And yes, when I first heard what it was, I pretended to know so that I wouldn't look dumb. Have you ever done that? Sometimes it's easier, as long as you don't get asked questions . . . before you can Wikipedia it!
These canvases remind me of CMYK, and are simple to make (beginning Podgers take note). If these colors aren't your palette, just use some that are. I'd love to see the same in blues and greens. Visit the tutorial to learn how to get your own CMYK wall art.
