I really hope to see a fresh captivating design and different colours. The last 3 years really were bland in the design department. I am so done with these spheres, beads, dandelions, pearls, and I would love to see something different and not necessarily something geometric. For me geometric shapes are very unwelcoming.
Colourwise, I like to see the Portuguese colours, which look very expensive and royal, but also quite warm and friendly. Gold, green and dark red would be a break from the common purple, blue and teal of recent years.
The scoreboard could use a make-over as well. Recently it got very boring. I know it is about numbers, but we do not have to be reminded of Microsoft Excel too much. I like it when it plays with maps. Why was the stunning scoreboard of Oslo 1996 never redone?
My favourite slogan for 2018 would be Salvador's own words "Music is Feeling".
But I would have also loved to see something that included "unstoppable" in 2015, and it didn't happen.
