      @developers
      Is there a way to modify dust layer color
      to be transparent (instead of white) for low (near zero) dust load ?

      It was available last year but with the latest update the outcome is not so good.

        Yes it was much better.
        I’ve tried to replace the white = 0μg/m3 by black = 0μg/m3, but the outline of countries disappear because they are now in black. Previously the sea was dark grey and land light grey. It is the reason why probably colours have been modified.
        Now the best compromise seems to be a medium grey (RGB 80,80,80) for 0μg/m3 as shown below.
        If you like, you just need to change the first line=0 in colour setting for dust: Replace (171,171,171) by (80,80,80) and save.
        Then if you don’t like, you can come back to the current default setting.

          Thank you!
          Unfortunately the medium grey for low dust load looks like a "smog".
          imho I preffer white for "no dust"
          (and I expect Windy developers to turn it transparent).
          My color pallete looks like

            That shows the relativity of « tastes and colours »....!
            The near zero dust in white, for me, looks like cloud/fog !

            Then I don’t know what is the significant threshold of dust in the air (to produce an effect on visibility, rain colouring, health...). So the map could be simplified if very low content of dust is ignored:

              100μg/m3 is a good threshold (from my experience) as indicates visibility less than 10km.

                also puts the threshold (yellow) in 80~160 μg/m3

                  Thank you, that’s interesting.
                  So I have replaced 10μg/m3 by 40μg/m3 to have a fringe of light brown for a better transition with blue that I use for « no dust ». And kept 80μg/m3 with darker brown.
