Many years ago I seemed to adopt the name lady in white, followed by my white slipcover iconic sofas... and then my decor in white followed. After many house remodels I now have my signature formula that I apply over and over.
I have just been working on a couple of small jobs and the choice of which white paint to choose can be overwhelming. There are so many great paints, but lately I have kept it simple. Gliden Paint, Bright White. This is the base white that tints are added to if other tones are desired, but I like the purity of the base. On walls I use eggshell for a slight sheen and then gloss on all trim.
My other favorite decor is taken from a commonly found detail in England, more for protection of walls in entry ways of dining areas, by installing a chair rail (molding) 36" from the ground. Then installing anaglypta paper below, which comes in many relief designs, and is then painted in eggshell white or a complimentary color.
When I do a room that I feel is too causal for the chair rail and anglypa paper, I simply paint a different color from the floor up (36"). This is a common decor choice in Morocco or Greece.
I decorate bathrooms and kitchens with white tile and marble mostly, but I do like to add little moments with either a tiny bit of color or white on white texture flowed into basic white subway tile.
