      Hi, the colour scale in the settings (default) doesn’t match what’s shown on the map. Where the totals are 1 mm, the scale should show blue, but there’s no blue on the map (or rather, the colour for zero is shown instead).
      It doesn’t work even if I adjust the scale and add, say, 0.5 mm; the change isn’t reflected at all. Yet for the Rain, thunder layer, even half-step works. Thank you for your help.

        Thanks for pointing this out, I can see why it looks confusing. Rain accumulation uses the accumulation rendering, so it may not behave exactly the same way as the Rain, thunder layer, especially around very low values near zero. That said, if 1 mm is being shown with the zero colour and custom scale changes are not reflected, that does sound like something we should check rather than expected behaviour. Could you please add your platform and version, web or app, browser/device, and ideally a screenshot with the picker showing 1 mm plus the colour scale settings? That will make it much easier for us to reproduce it.

          Hi @mirekhakl this is a technical limitation of how we render color gradients on the map, you can work around it by reducing the largest color gradient stop from 8000 to around 2000 or lower.
