What does the purple focus spot mean on the a7r iv?

When you say low light, how much low light we talking? And which lens? That way others can try if possible.


Here's an example of where it happened with the Sigma 105 1.4.

ISO was set to 1250 with a 1/125 Shutter speed +1.0 EV - so not excessively low light. Metered for highlights. Couldn't lock on the faces of sculptures themselves, had to use an area where part of the sculpture was next to the sky to acquire focus lock.
