Different colors of eyeshadow, magnetic lashes etc I need help please?

I’m hoping to attempt to practice a blue eyeshadow look but my only thought is I have green eyes and blonde hair I don’t know if my eye color can look good with blue shadow. Any other ideas at to what colors I should try on my eyes? And I’m trying to practice with false eyelashes but they are magnetic not the kind you use glue on. Mine are accents and have been hard to put on. I have a general idea but I can’t get the lash onto my own eyelashes can anyone help please?
