Rai Gulp's original logo followed the logo designs of Rai's three flagship channels, Rai Uno, Rai Due, and Rai Tre. Its logo had blue color but appeared in a yellow background in its idents (Rai 1, Rai 2, and Rai 3 had their idents between 2003 and 2010 showing their colors in white and in their respective colors, blue, red, and green).
Rai Gulp changed its logo to follow the styles of Rai's other digital channels (Rai Gulp is a TV channel available only on digital TV). Rai Gulp's logo had a unique pattern, wherein the square on the right had a triangle below it, making it resemble a speech box.
In 2010, Rai launched its new corporate logo. Rai Gulp slightly modified its logo, following the design of its sister channels, dropping the butterfly symbol and maintaining the light blue color and speechbox shape of the previous logo, which was also adopted by another youth-oriented channel, Rai YoYo (both channels target younger audiences). When this logo was launched they have the old 2008 idents instead of the new bumpers. The new bumpers debuted on November 2010.
2017-presentFollowing on from the rebrand of Rai's 4 main channels, Rai Gulp along with Rai's other main thematic channels were rebranded to match that of Rai 1, 2, 3, 4 on the 10th April 2017. Rai Gulp kept its light blue color but ditched the speechbox shape of the previous logo along with Rai Yoyo. They also changed their idents featuring teenage characters with cube-shaped heads doing their own thing on screen like taking selfies, playing music etc (this represents Rai Gulp's new-found teenage audience) and they also now use lime green and magenta as secondary colors on screen.
