Nice. Yellow seems to have a tad more stringing though, no? Did you change any other settings, other than layer height?

You’re right, and I think it’s actually the filament, because a separate yellow print with the regular settings I used looked more stringy than usual as well. I’m probably gonna do some more tests more controlled to see for sure though.
Had the same issue when I switched to a new brand of PLA. The stringing is minute, but still noticeable. (Check your DMs, btw.)
