Hairdressers help ???

Hey I’m looking to get my boyfriends color of blonde but not sure what shade he is. It’s sometimes a little grayish ? It’s definitely a rare color. He’s a natural blonde so if someone could help me with how I should get my hair color to the same as his

Much appreciated

And here’s mine

I know I know it’s fucking yellow I don’t know what to do with it I’ve tryed purple shampoo and no luck. I’m probably gonna have to bleach it again

UPDATE: so I had some dark spots I went to Sally’s and got some bleach and the wells t18 toner like yinz said too and waaa-laa !!!! Thanks guys so much
