Betta Fish: What type of betta is he?

Heyy! So I just got this lil "guy" that I rescued:) The person told me that this fish was a female but I'm not sure? And also, I've never seen a betta with this color/morph, does anyone have an idea?
The ends of the fins are clear, the body is mostly yellowish, we can see a blood vessel(I guess?), some of the scales are blue, on his head there's a bit of pink and under it its super white and iridescent. Thank you🫶
