The Flash is a superhero that was created in 1940 by Harry Lampert and is owned by DC comics.  The logo is very popular and recognizable among those who love comics or superheros. The logo shown here look like a a vector image of the original.  The bright colors used in the logo help with recognition.  I don't think the logo has changed since it was created in 1940 so this would also help with recognition as it has stayed consistent throughout the years. The colors are meant to represent bravery, speed, and optimism.
