If the orange annoys you then simply take the fan off - mask all the non orange bits - get some spray paint (what ever colour turns you on) and paint the sucker.

Personally I don't mind the "community centre" orange that TT use

or you can change the 120mm fan with one that has a colour you approve of.

Punter 2: "why not?"

Punter 1: "Don't like the colour."
