For Crayola, going Green is a black and white issue. In honor of Earth Day, Crayola will switch to black and white packaging.

Not only will these boxes save energy, resources and 30-40% of their packaging cost, but they will also highlight Crayola's Green initiatives and inspire others to protect the planet!

Print ads created using photochromic ink will change from black and white to color once they are exposed to sunlight.
