Sativa or Indica

I chose both because I've only tried hybrid strains. However, I just tried an unknown strain, and I was getting some intense/colorful visuals in my mind. It's hard to explain, not like hallucinations or anything. But I'm pretty sure this strain was sativa-dominant because of that, and it felt really good. So I'd choose Sativa if that's the case.

 

You sure can get some signs on which is more dominant,
For example: a indica bud often gives a strong physical body high that will make you "couch-locked" and a deep relaxation feeling compared to a sativa, which is known to be more energetic and uplifting. Example of Indica dominant strains are the Kush strains and example of Sativa dominant strains are the Haze variations.
