Is it possible to display individual point clouds in different colors? Would be very helpful to distinguish them during registration.

Thanks,
Aaron

Of course, just select each cloud and use "Edit > Colors > Set unique".

Perfect, thank you!

I have the same question - I would like to color two point clouds different colors to distinguish them. However, I want to do this so I can edit and delete some outlier points, so I would like the color display to reversible, so that I can flip back and forth between the RGB color in the point cloud and a single fixed color. It seems the suggestion to "Edit > Colors > Set unique" is permanent. Is there a reversible way to do this?

I think the easiest way would be to add 'constant' scalar fields ('Edit > Scalar fields > add constant SF'). You can set both SFs with the same constant value. At first they will both appear in blue (as they have the same display settings) but then you can change the color scale used to display one of them so that they appear different.

And then you can easily switch between the (constant) SF and the original RGB colors with the 'colors' field of the cloud properties (or the 'S' and 'C' shortcuts)

That works very well, thanks!

Is it possible to automate this process?
I have hundreds of objects I want to colorize (only for demonstration purposes).
