Help IDing strain

[Jbreezy]

I had a few plants growing this year, two of which I thought were the same strain, but recently one of them started going purple at the tops. The two strains are white banner and black indica, can anyone help identify which of those two strains is more likely to turn purple, until now I thought they were both black indica but now I obviously have my doubts.

Couple of pics for yah, they are just the few remaining buds that I didn’t bother to trim after harvesting plant.

Most likely the same strain.

It’s turning purple as it was probably exposed to cold temps. Why the other one didn’t turn as well? Maybe it wasn’t cold enough for that phenotype? <<shrug>>

That is my guess.
