There's not much wondering on how I made these, but I'm explaining it anyway.

I got the idea while navigating into UEFAs official website, and at the fans section I came accross through the banner below, and thought to develope it in another way.

So, I managed to get the blue background artwork from the website, and hued and saturated it to match somehow the original color from the banner artwork (that was a really big deal). And I composed the logos and text into it and customized them to adapt with the format of each social network.
