I don't think orange will become available once the ELL transfers to a
TOC in November. In fact its presence will increase on the LU map as
the WLL, NLL, Gob-Lin and Watford DC lines are added.

OK, here's a question. If (and it's a big if) an additional line is
opened at some future point, what colour will provide maximum contrast
with all existing lines.

ISTR official maps showing Chelsea-Hackney in lime green. Quite repulsive.

(Pratchett fans may NOT nominate octarine.)

One of the shades of black not currently in use, then?

Interesting - thanks. On Wednesday I gave 'silver' as the colour for
the Jubilee line and this was 'correct', although I see it's
officially 'light grey'.

It's disappointing that it's officially recorded as light grey - given
that the line was named in honour of Her Majesty's Silver Jubilee,
it's fairly obvious what the intent was when choosing the colour. The
fact that it was arguably the best available colour for contrast with
all existing lines was serendipity.

At the time I am sure that I heard that the choice was driven by the
very restricted range of colours available (then?) for enamel signs.

I don't recollect the silver of the Jubilee ever being mentioned in
connection with the line colour.

Cheers,

I think a good line would be across south London to Heathrow. This
line, which I call the Charlton-Heston Line, would be coloured deep
purple.

Another line from Croydon to the city (the Shirley-Temple Line) would
be coloured black, and the Northern changed to cyan.

The Line was named after the River Fleet as the Fleet Line and
presumably grey was a convenient 'spare' colour. It was fortunate that
when Horace Cutler renamed it as the Jubilee Line as a PR stunt c.1977
the 'grey' colour could be rechristened as 'silver'.
