What color were the firemen's uniforms?

There is a brief description of the color of his helmet in
the first chapter which states,

“ He hung up his black
beetle-colored helmet and shined it; he hung his flameproof jacket neatly.” 
 

This is really the only reference to the color of his
uniform; however, we would assume that because the helmet is black, that the uniform
would be black also.  In addition to this, the uniform has two symbols on it which would
probably be some type of contrasting color – these symbols would be those of the phoenix
and the salamander.
