Is your feature request related to a problem? Please describe.

Currently point clouds are visualized as white points on black background, and this is not comfortable to work with.

Describe the solution you'd like

Add an ability to customize point cloud colors (foreground and background). In my opinion, gray points on white background look much more ergonomically, and I can annotate point clouds faster and more precisely.
