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.

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.

(Pratchett fans may NOT nominate octarine.)
