In 2008, like the Buenos Aires version, a new logo is released, a twelve-pointed sun with a central hole in the shape of a circle, with the colors red, orange, yellow and violet (clockwise); the union of the colors is oblique with respect to the central hole. It is a bit thinner and brighter. Under it said CANAL SIETE.

In 2011, the logo was restyled by the American company C&G Partners, which created the original isotype of the Tetracolor sun in 1994. The sun becomes a little thicker, with the hole a little smaller and the union of the colors is perpendicular to the hole. Below it it says: el siete until 2015.
