What color are these walls?

I found a house i really like, and i want to paint my house the same color. I am putting on the primer paint right now so i;ll be ready to paint the real colors soon but i dont know how i would go about finding what colors these are.

Does anyone know how i would go about finding what colors the walls are?

I am looking at the walls of the living room, kitchen and dining room

Heres is the pictures of the house

Thanks!
