Deep Blue and Floral Wallpapers: Bold Scandinavian Interior in Goteborg

They say that a light base and calm color palette are a safe and winning starting choice for creating a beautiful interior. But in this apartment in an old house in Swedish Goteborg, everything is completely the opposite: the interior base is very active thanks to a deep blue tone and wallpapers and patterns used as wall decoration. Such a choice seems quite bold, considering the more traditional style of interiors, but in the end, it turned out that designers didn't make a mistake — the apartment looks striking and vibrant. What do you think of this design?
