On all printed publicity for underground and buses, the phrase 'Mayor
of London' is shown. Why is the ON at the end on LONDON always in red
whilst the rest of the text is in blue?


I think this was an initiative by London Tourist Board / Visit London after
the 9/11 terrorist attacks - to emphasise the point that London was "On" by
which I guess they meant "We're open for business as normal". It seems to
have stuck ever since.
