The press conference with the full details about the slogan, visual identity, tickets, participating countries, et cetera will start soon. I don't know wether it will be broadcasted on RTP 3 or not, but I think so.
The logo is cool! Totally not what I expected, but really great. About the slogan, I'm not that enthusiastic. It feels kinda.. cheesy. I get the reference to the ocean theme but.. meh.
"Europe is a collective of many, and this has also inspired RTP’s design team to introduce multiple logos for 2018, rather than a single image. The main logo depicting a shell comes with twelve other derivations, which are predicated on the concept of the varying life in the oceans and depict the wonders of a floating world, such as plankton and a range of other organisms which are essential for balance in aquatic ecosystems."
Not a horrible logo and slogan, but a very different one comparing to former years. Indeed a statement from Portugal after all the recent talks about the garbage that people put in our seas, nice job RTP!
