Adjust color scale to make it easier to perceive the data

[Wosi]

First of all: Thank you very much for making this project. It is very helpful!

I think the color scale makes it hard to differntiate incidence values above 50. Compare these two charts from https://semohr.github.io/risikogebiete_deutschland/ and https://www.risklayer-explorer.com/event/100/detail which show (almost) the same data:

I think it would help to use a similar color scale on this site as well.
Keep up the good work!

Thank you for your input. I change the colour of the high incidence groups to match the risklayer scheme. I still see a problem for people with green-red colour blindness on both visualisations tho.
