Studio White isn’t really a color, it is the absence of reflective color and the fullness of light. Studio White is an exercise in smart commerce, it’s the thing that a property owner will do to minimize maintenance. Simply, it is just using plain white semi-gloss on a wall (and flat on an actual art gallery wall) with no pigmentation. The paint is pure white because pure white is easier to touch up, it is easier to find, easier to match. And the lack of pigmentation creates something kind of wonderful, it creates a canvas onto which the prospective inhabitants can see their future.
Studio White might vary between manufacturers. Glidden’s Studio White will be difference from Behr and different from PPG. They all have a slightly different luminosity to their light, and if you put down Behr Premium Semi Gloss, you can’t touch it up with Behr i-300 Semi Glass. They won’t match. But for years and years, you will be able to touch up with Behr Premium Semi Gloss. And if you are are smart and have a good memory, all of your rentals will use the same paint, so you can fix them all from the same paint.
The economics of the opportunity present themselves in such a way that the property owner releases himself or herself from the need for tinted paint not to show the coal dust, to a decent white paint, which is going to get dirty regardless.
