Gui Boratto (born 1974 in São Paulo) is a Brazilian electronic music producer. He started his career working in the Publicity sector in 1989.

His album Chromophobia was awarded the title of Mixmag Album of the Month. Regarding why he chose the name Chromophobia, Boratto said: "The same meaning as monochromatism in architecture, which means simplicity. That’s all. I don’t have a morbid fear of colors at all. But also, I was ironic. My music is really colorful."

On stage, Gui uses a laptop equipped with Ableton Live, a Jazz Mutant Lemur, a monome and an Evolution Uc33e, and he sometimes even invites a guitar player to join him.
