As of now the color shown next to a text value, say PM2.5, is based on a range of values, such as green for Good, yellow for Moderate etc.
I think it would make sense to instead smoothly transition the color between those ranges. Say 0-10 is green and 10-20 is yellow.
So when the value is 5 it should be 50% green and 50% yellow.
These colors indicate how “healthy” the values are but they make a lot of less sense now, for example going from 9.9 as green to 10.0 as yellow isn’t actually any meaningful change but it shows up as a whole different color.
Maybe the same can also be said for the LEDs?
