An interesting presentation at Colourlovers, a website that focuses on design and color. Presented today to contrast the classic style London used in 1948 with the grotesque design and garish colors selected for 2012. I'm not the first to comment on the 2012 logo. This from Wiki:
Early public reaction to the logo, as measured by a poll on the BBC website, was largely negative: more than 80% of votes gave the logo the lowest possible rating... It was noted that the logo resembles an image of the cartoon character Lisa Simpson performing fellatio and others have complained that it looks like a distorted Swastika.Apart from the design itself, the most notable fact is that this is the first time ever in the history of the Olympics that the logo will be produced in a variety of colors.
A segment of animated footage released at the same time as the logo was reported to trigger seizures in a small number of people with photosensitive epilepsy. The charity Epilepsy Action received telephone calls from people who had had seizures after watching the sequence on TV…
Why? Oh... maybe it has something to do with this: "Sponsors have also incorporated their company colours in the logo, notable examples include Lloyds TSB and Adidas."
