for a website "[login to view URL]" a SVG logo is needed that is modern, clean and crisp on the one hand and traditional on the other hand. That means that it takes into the typical Bavarian typo and the Bavarian blue / white.
The logo should be - in a second variation - compact so that it can also be used as an [login to view URL], or favicon (if necessary without typo, one letter, or something like that).
To get an idea, i attached a logo from a competitor which is nice. Of course we should not copy that! But i love the idea with the bavarian blue background and the typical bavarian white diamond. Simple and clean.
