Change the colour coding of the AQI app just a little
first of all thanks a lot for this great app! The latest versions combine the advantages of different AQI apps in one, great work!
I just have a minor suggestion for the colour coding of the different levels of pollution. I would actually switch the two colours of the highest levels, with very unhealthy being dark read and hazardous being purple. The reason is because first of all, from yellow on the red in the colour spectrum usually gets darker (yellow, orange, light red, deep red), so logically deep red would follow light red. Second, if you have a wound e.g. because of freezing, it changes its colour from bright red to dark red, to purple and finally to black. With black being the flesh froze off. That migh be a warning metaphor in terms of colour.
Let me know what you gus think! Thanks,
