Seems like a nice lens. Can’t find anywhere in literature - am I making a mistake in my search parameters?

A lensed galaxy is a different colour from the lensing galaxy, because the lensed galaxy is further away.
If it is the same colour as the target galaxy, I would say that it is part of the galaxy.

The story of a gravitational lens Zooniverse

Fairly sure it doesn’t always have to be a completely different colour. There isn’t enough definition to see clearly here but I can’t really see it being a part of that galaxy. Equally, the lens isn’t exactly 100% clear enough to make out the primary colour but it seems to be a little more red than the galaxy. Anyone got anything to add?
