It has long been known that colour plays a major role in our everyday lives and ultimately also influences our sense of wellbeing. Johann Wolfgang von Goethe published his most comprehensive work "Theory of Colours" (“Zur Farbenlehre”) back in 1810. He attributed colours higher order characteristics which have an impact on every aspect of our lives. So, it should come as no surprise that companies in particular put a lot of thought into colours and their impact when looking at their corporate design. One of the world’s best-known logos is the Lufthansa crane and – on the occasion of its 100th anniversary – it has now had a makeover. But it is not just Lufthansa’s logo, but also its entire corporate identity that has been given a new, contemporary appearance – something we can look forward to seeing when we next visit a German airport. Lufthansa head designer Ronald Wild spoke to us about his work and the importance of blue and yellow.
