Discussion on another forum which is not allowed to be mentioned on here regarding an 'automaatic' weather report feed to aircraft which uses a 'colour state' system.
The colour states reported are totally unlike the system used here, it being an American system giving visibilities in statute miles and using only 4 'colour states' starting with 'green' as the best weather and having no 'white' or 'yellow 1/2'..
You can view the colour states used at

I've pointed out this is a potential flight safety hazard' I don't even know if the system has been approved by the CAA.
