Valspar's White Scallion is a similar color.

It's just a white, probably from Sherwin Williams

I am the homeowner, the walls are Sherwin Williams Ivory Lace 7013.

Are the walls and ceiling the same color?

No the ceiling is white, I think all of my ceilings and trim are Benjamin Moore White Dove.

Love this clean simple white look. I am designing my sewing studio and am interested in the taller open shelving against the wall ?
Are the shelves adjustable ? And where did you purchase them ? ~Thanks for your time.

The tall shelves are from a store called More Space Place. They specialize in custom shelving, Murphy beds, storage, etc. the configurations are fully customizable. Someone came to my house and measured the space then I told her what I needed for storage and she came up with a design. Someone came and installed it. The shelves are adjustable once the whole unit is installed.
