To Anon(s) who are wondering why Fredrick Brennan's letter "Q" is blue and why Fredrick Brennan is often associated with that color…I cannot say for certain, but I am speculating from what I know about Mr.Wheels.
Fredrick Brennan has brittle bone disease (osteogenesis imperfecta).

One of the physical occurrences of this disease is that the eyes take on a blue hue.
This is the only reason why I can think of why Fredrick received a blue Q and associates with the color blue.
