Rai 4

1st Logo (2008-2010)
Logo: We see several purple fluorescent lines moving across the screen, leaving purple particles behind. As the screen moves, we see the lines stopping and forming the number "4", then a flash appears and we see the giant "4" in a different perspective. The Rai butterfly logo in purple appears next to the "4" as a purple square appears around it. Finally, the complete logo flashes and moves to the center.

Technique: CGI. This was designed by Frame by Frame.

Audio: A quiet techno theme, along with an announcer saying the channel's name.

2nd Logo (2010-2016)
Logo: Practically the same as the previous logo, but the Rai butterfly logo is replaced by the word "Rai" in purple, and the square appears around it instead of the "4".

Technique: Same as the previous logo.

Audio: Same as the previous logo.

3rd Logo (2016-)
