Thank you for the replies! Unfortunately I can't seem to find this setting in the Android app. Either way, wouldn't it make sense to adjust the default?

Some color maps, e.g., the one for wind speed, repeat some very similar colors for lower and higher values. I would like to see the option to select a perceptually uniform color map that goes from dark to bright (like matplotlib's viridis, for example), or just from blue to red without so many different hues in between

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.
