Spoiler about Hong Lu:

Should the heterochromia tag apply to him? We learn in canto 8 that he wasn't born with a teal eye, but that it was placed in his eye socket by his grandmother to act as a bio camera.

You should put "spoiler" in brackets ([]) before spoilers to actually spoil them. like this
But anyways, it's not natural heteorchromia, but it's still 2 different eye colours so it qualifies for heteorchromia. If you got other questions, just ask in the limbus forums.
