Hi Elin,
There is unfortunately no way to see statistics for daylight at the moment. We have been working on extending statistics for sun hours and solar energy. We have ambitions to provide statistics for daylight in the future.
There is also no way to change the color scheme for this analysis. We are happy you reached out and voiced your request. We always take user feedback seriously when prioritizing new functionality.
P.s. You might already know this, but you can use the inspect tool to see daylight in selected points. It does not solve all your needs, but I thought I would mention it.
Kind regards,
Andrea
