This fun color theory t-shirt design is available on Threadless. It has blue ink printed on a red t-shirt, visually making the letters appear purple.
The designer’s tongue-in-cheek saying cleverly plays on a phrase — (fill in the blank) is the new black — that is overused by the media when talking about color.
If only mixing blue and red did always produce purple. Anyone that has mixed colors – whether with paint or dye or clay – knows that what when you mix two colors, the result may not always be what you expect. But that’s a post for another day.
