Scale and color

Hi guys. 
Two questions. 

1. When importing an .E57 file the point cloud is quite small, which I am sure makes really good sense, but the problem is previewing other GH geometry. See attached. Does anybody have a good idea how to solve this?

2. Is it possible to extract/find the color of each point in the cloud? I am experimenting in automatically identifying window positions. Any other ideas are ofcourse also very welcome.

Thanks. 

Best regards Rasmus
