When Professor Cobalt wants to get paid, he sends a color invoice.

This campaign used a tiny budget to convince HP’s small business audience that color printing is effective and affordable. We created the character Professor Cobalt, a socially awkward champion of color who comes alive when talking about the virtues of red, yellow, blue and green.

The campaign featured a website, viral videos and DM components all centered around the message that HP makes creating color marketing materials affordable for the small business owner.
