Hair color advice. Do you think I should go dark?

Hi lovelies I’d really love some advice. I’ve been thinking of dying my hair for quite some time but I’ve always been to afraid to commit. I’m graduating this year so I feel like this is the best time to do it a nice time for a change (I’ve never dyed my hair and I’ve always had the same haircut) however I’m in a bit of a dilemma I’m unsure what color to do. Atm I’m thinking either a dark cool tone brown or a light blond but I’m very indecisive and can’t choose would really love some opinions and advice on what you guys think might suit me?

This is the dark color I’m thinking:

And this is the kinda blond:

And this is me:
