Formidable!
Very nice indeed - merci bien!
One minor suggestion, why not align your colour codes to those used by the military (cloudbase pertains to SCT, not BKN):
Black - Airfield closed for non-Met reasons.
Red - Cloud under 200ft, and/or Visibility under 800m.
Amber - Better than Red, but cloud under 300ft, and/or visibility under 1600m.
Yellow - Better than Amber, but cloud under 700ft, and/or visibility under 3700m.
Green - Better than Yellow, but cloud under 1500ft, and/or visibility under 5km.
White - Better than Green, but Cloud under 2500ft, and/or visibility under 8km.
Blue - Cloud 2500ft or above and visibility 8km or more.
Also, in the UK one can be under IFR in VMC.....
