A young Clitocybe nuda?

OP here but on my pc. the color looks right but look how small the caps are.

They are really young. The cap would have expanded if you left it for another few days/week or more.
Keep in mind some Cortinarius species are purplish too, and they can be very poisonous. If your specimens were older you could do a spore print: Cltocybe nuda has a pale/pinkish spore print while Cortinarius species are usually brownish. Cortinarius species also have a "cortina" when young, which looks sort of like a cobweb covering (Google it). I can't see it in your pic but you should check for it; the cortina can sometimes be hard to see or rubs off.
If there are more, check in a week or so. Wait until the caps fully expand. But don't eat them regardless of whether you think it is a blewit (C. nuda) or not, because you aren't an expert and you don't want to accidentally eat a Cortinarius.
It the purple from bruising or is that yellow tint on the bottom of the image bruising?

honestly, no clue. the purple is its original color i believe
