      There is no way to customise the steps of the colour scale.
      But I don’t think that remembering 10 colours is so difficult. I have 13 for my own wind scale, and never use the legend.
      As @Yves70 said, at the end, the weather picker is the best tool to know the exact rain accumulation in the areas where your colours show high values.
      btw could you post a screenshot of a rain accumulation map with your customised colours. That should be interesting for Windy users.

        Many thanks to you and @Yves70 for your responses and apologies for the late reply. I'm new to the forum and did not think there had been any replies. I do use the weather picker all the time, but find the fixed legend scale inelegant.

        The legend sample I enclosed came from an accumulated rainfall forecast map provided by the Australian Bureau of Meteorology. They provide a 1-4, 5-8 and 1-8 day forecasts for our region using combined input from 5 models, including the ECMWF. They are very useful for identifying the potential for flooding from multiday rainfall systems like east coast lows and tropical cyclones.

          Your Rain accumulation map is excellent. If you want to get it even more similar to the map provided by BOM, let me see your customized color scale for Rain accumulation: Show a screenshot of your setting, like this one, to see how your scale steps are fitted.

            Thanks. Here are my settings. I just estimated the colours. The upper reds were a failed attempt to make the legend more helpful.

              More than the fixed colour scale at bottom right corner of the screen, the fact that colours are smoothed/blended in Windy does not allow to see clearly the different colour ranges. You can overcome this problem and get a discrete (not smoothed) scale with only a small blending between each colour range:

              If you want to get the code in order to use directly this colour scale, just let me know. That's easier instead of adding lines.
              To make a comparison with this colour scale and your own scale, you may use the new one with a different browser without logging in.

              Personally I would use the 400 - 500mm red for 500 -1000mm and vice versa.

                @idefix37 Would it be still possible to grab your colour code for the rain accumulation?

                  You mean the code of the colour settings here above that I made for @atmosj ?
                  I am not sure to have it still, I check and come back later.

                    @idefix37 Yes please, I was hoping you would still have these color codes.

                      I’ve lost the file so I had to redo it.
                      I have set the colour precisely to the original colour scale, but I have modified the upper end above 400mm which is to low for 10 days accumulation in tropical areas.

                      Here is the code:

                      [[0,[255,255,255]],
                      [0.5,[255,255,255]],
                      [1,[247,185,95]],
                      [4.5,[247,185,95]],
                      [5,[253,175,42]],
                      [9.5,[253,175,42]],
                      [10,[254,252,55]],
                      [14,[254,252,55]],
                      [15,[180,253,51]],
                      [24,[180,253,51]],
                      [25,[86,253,48]],
                      [49,[86,253,48]],
                      [50,[35,228,155]],
                      [99,[35,228,155]],
                      [100,[30,167,252]],
                      [149,[30,167,252]],
                      [150,[65,72,251]],
                      [199,[65,72,251]],
                      [200,[176,37,251]],
                      [299,[176,37,251]],
                      [300,[251,40,251]],
                      [399,[251,40,251]],
                      [400,[253,80,156]],
                      [698,[253,80,156]],
                      [700,[244,10,75]],
                      [998,[244,10,75]],
                      [1000,[143,11,40]]]

                      You must modify the color settings on the website. That’s not possible from the phone app. But the same modification will be applied to all your devices.
                      Go to Settings
                      Scroll down and choose Customize color scale
                      Select overlay:
                      Rain accumulation
                      At bottom of page find the line Import/export
                      Click on [view code] to open a window pop up
                      Delete the text code in this window
                      Select and copy all lines of code here above and paste them in the window
                      Press [Import Gradient]
                      Press Save
                      You can come back to the default Windy settings at any time by pressing Load defaults

                      It gives this scale and map:

                      0C575932-540D-43F6-86C9-740F12DCA482.jpeg

                      Hope you’ll use it.

                        @idefix37 Thank you, really appreciate your help :)

                        I've just change the 0mm & 0.5mm RGB codes back to the default grey.

                        The new colour codes really help the different mm amounts pop.

                          Yes, the white used by this colour scale does not enable to get details of the base map. But you could use a lighter grey such as 130,130,130 to avoid too much contrast. And the problem will be the same with the bright yellow to see the locations in base map.
                          Another glitch is the 2 red colours which are difficult to distinguish.
                          If you like the overall scale, from this base you can make some small additional adjustments mainly because this colour scale has probably been designed for black printed map and labels.

                            I come back on the upper end of the colour scale. I was not satisfied with the red colours and with 10 days accumulation in tropical area where it is necessary to have a semi logarithmic scale.
                            So I propose these steps:
                            …
                            300mm
                            400mm
                            700mm
                            1200mm

                            With the following code from 300mm:
                            …
                            [300,[251,40,251]],
                            [399,[251,40,251]],
                            [400,[240,0,50]],
                            [698,[240,0,50]],
                            [700,[210,11,40]],
                            [1150,[210,11,40]],
                            [1200,[143,11,40]]]

                            Today, as example, using this setting, on 10 days accumulation, in the East of Cairns ACCESS gives this map:

                            44C0FF35-B0C6-477D-9F90-1DB96E7483EE.jpeg

                            For the light grey, I used 170,170,170

                                Fine but you have one line missing between 200 and 300:
                                [299,[176,37,251]],

                                And try for 0 and 0.5 a lighter grey
                                [[0,[130,130,130]],
                                [0.5,[130,130,130]],
