Comparing a new batch against an old one. A slightly off-colour batch is different in a way that may be nothing. Imprint is the strongest signal, colour is the weakest, and the shape only narrows the manufacturer.
Worth repeating that this is not medical advice and the answer often depends on who you are.
Imprint first, country second, colour last. And photograph both sides in daylight. Side effects was my main issue with a slightly off-colour batch too.

Pharmacist. Two minutes. Same for me with a slightly off-colour batch, unfortunately.
Daylight, no flash.
If it came with a repeat slip, the slip beats every database.
