Hi Piotr,

The code as below shows how to replace a color to black just like the screen shot shows:

 private void DisplayMap_Load(object sender, EventArgs e)
    {
        winformsMap1.MapUnit = GeographyUnit.Meter;
        winformsMap1.BackgroundOverlay.BackgroundBrush = new GeoSolidBrush(GeoColor.GeographicColors.ShallowOcean);

        OpenStreetMapLayer layer = new OpenStreetMapLayer();

        // This code change the color
        layer.ColorMappings.Clear();
        layer.ColorMappings.Add(GeoColor.FromArgb(255, 242, 239, 233), GeoColors.Black);
        // Code end


        LayerOverlay worldMapKitDesktopOverlay = new LayerOverlay();
        worldMapKitDesktopOverlay.Layers.Add(layer);
        winformsMap1.Overlays.Add(worldMapKitDesktopOverlay);

        winformsMap1.CurrentExtent = new RectangleShape(-2000000, 2000000, 2000000, -2000000);

        winformsMap1.Refresh();
    }

Regards,

Don
