Great - I hope you can understand the code. But remember that PHP
Weather itself is based on a Perl script called Geo::METAR:

  http://jeremy.zawodny.com/perl/Geo-METAR/

So perhaps it would be easier for you to look at this instead. But
you'll find that PHP Weather recognises things that Geo::METAR doesn't
unless it's been updated, but it look like that.

Thanks!

Doesn't the regular visibility and cloud-group information already
include the information given by the colours?

If not, then I guess that we could include the code, but if it's a
special code that's only used at a handful of stations in the UK, then
perhaps it's too much trouble to be worth it... I don't know.
