Blue

[HoratioHB]

So, a previous thread asked about some blue lights you might just see in Plymouth Sound. It raised a question I've often wondered about - why isn't blue used regularly these days? It certainly was in days gone by but is not part of the colregs or any of the buoyage systems that I am familiar with (that of course is guaranteed to get an expert to shoot me down). If you take the fact that a single white light can have multiple meanings, anchor light/stern light etc then why not use blue for one of them - personally I would like to see anchor lights changed.
So why can't we have blue anchor lights???

Remember Hofnung's advice to tourists- 'All London brothels display a blue light'. Could get a bit confusing near the bottom of Union Street.

There are blue leading lights for passing under the Severn bridges. I suppose they could lead to a brothel in Chepstow but I havent looked

The emergency wreck marking buoy has an alternating yellow and blue light.

Out of interest what was the answer? I was in the sound at the tail end of last year and noticed them, it had been 30 years since I had last sailed there and was quite sure I had not seen them before. I suspect there are there the the RN to use.

I thought ali police stations had a Blue Lamp outside. Police cars in many countries have blue and red flashing lights.

Or am I having an "over my head" Whoosh moment?

Everything looks blue in low light. It's to do with the light receptors in the eye. Blue lights may be confused with natural highlights if they're not very bright.

You are correct. Just checked the chart on VisitMyHarbour and at Withyhedge there is a Fl (2) Bu.5s 10M and another near the Bridge

You are.

You are probably too young to remember it was in a competition for "misleading advice for foreign tourists".

Together with (among others)

On entering a railway carriage, be sure to shake hands with all the occupants.

The 'advice to tourists included such gems as 'On entering a railway compartment, be sure to shake hands with all the occupants' and 'Have you tried the famous echo in the reading room of the British Museum?'

Without refering to a chart or QHM, I tink the blue lights on jenntcliff are for the R.N anchorage just north of the fort/breakwater. There again i could well be wrong.
