The mapping of colors is sometimes very ambiguous. In the screenshot above, for example, it is hard to tell in which regions wind speeds are around 0 km/h and where they are about 90 km/h. I imagine these colors are even harder to interpret for people with color vision deficiencies.
It would be nice if more brightness corresponded to higher wind speeds, temperatures etc., which for color ramps like these is not the case.
Edit: I noticed that these colors can now be customized. However, defining all these colors individually would be very cumbersome. I suggest implementing more sensible defaults.
