Gui Boratto (born 1974 in São Paulo) is a Brazilian electronic music producer. In the 1990s, he was a member of Sect.

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."
