Hi Adrian
The red color is the only remind issue when scanning with blue light or a laser.
For an obvious reason the red is absorbing the blue light so it can’t be fully reflect back to the sensors from the surface.
All other trouble colors was scanned without issues with laser mode or other modes using the dark mode scanning settings.
For the red I am using transparent 3D scan spray that helps to reflect the blue light better or a regular 3D spray.
I am afraid there is nothing else that can change the law of physics here.
You will need so strong laser power that would be too dangerous for the consumer usage and not really worth it.
Blue lights offers the best smooth results and accuracy in structured light technology. But as always there are cons.
Sorry that’s all I can offer you today with my reply.
