Help with these blues please

[Deborah]

On dunes, North Coast of Brittany today (Plouescat, Finistere). I think they’re all Common Blues? But apparently there’s a very ‘blue’ female form found here, and one of these females looks pretty blue to me... but maybe it was just the sunlight. Thanks for any help.

For me:
1 male Common Blue
2 blue female Common Blue
3 Brown Argus

Thank you. I couldn’t count how many I saw - which was amazing. It would’ve been nice to have seen something ‘special’ - but these were pretty special to me!
