[MainUI] Map pages have suboptimal defaults - use colours sparingly

[dilyanpalauzov]

When I define a Mapview item in BasicUI, or openHAB-Android, I see more colours, compared to a map page in openHAB 5.2.0 build 5199.

I find the presentation in BasicUI and openHAB-Android better than the default presentation of map pages in MainUI.

In openHAB-Android:

In BasicUI

In MainUI-

Page definition:

  "map1": {
    "class": "org.openhab.core.ui.components.RootUIComponent",
    "value": {
      "uid": "map1",
      "tags": [],
      "props": {
        "parameters": [],
        "parameterGroups": []
      },
      "timestamp": "Feb 27, 2026, 2:12:24 PM",
      "component": "oh-map-page",
      "config": {
        "label": "map1"
      },
      "slots": {
        "default": []
      }
    }
  },

You can try out different maps yourself, so why don't try them out and make a suggestion?

https://next.openhab.org/docs/ui/components/oh-map-page.html#tileLayerProvider says for tileLayerProvider:

The default is CartoDB, the variant depending on the dark mode setting.

My reading is that unless CartoDB is selected, there will be no adjustments for dark/light mode. As mentioned at #3929 one way to adjust for dark mode is in CSS to apply filter: invert(1) possibly also with hue-rotate(180deg). So the aim is twofold: get a map with more colours, which adjusts to dark/light mode.
