Nothing. In fac rumour has it that the white aspects are going to be
replaced with blue aspects, to match the blue aspects to be used on
the VLU signalling.

Buuut...If you do that, then they could be confused with lamps
associated with tripcock testers. Fun eh?

Other than white is also a valid TCT colour too , depending on the
location.

Bloody hell, yet another TLA. Whats TCT then?

And we've only had a "guess" so far that VLU is Victoria Line Upgrade. If
that's right, why is the Victoria Line changing to blue after nearly 40
years of white?
