Here's the poop. Projection screen paints are great and contain additional reflective ingredients, but they can be VERY expensive, like $500 expensive sometimes. Also, if you have a good "light controlled" room, eg, very few, or no windows, you will never need the added reflective ingredients.

BEHR has a color code called "Silver Screen", it's not fancy or pricey, BUT it DOES contain the proper combination and proportion of pigments to get the correct color reflectivity that a projection system requires.

Example, even though the color looks like a very light grey, it has a fair amount of reds and yellows in it. You can't see it in the paint once it's mixed, but, when the projected image reflects off the wall, a person's face, for instance, will possess the proper skin tones as reflected by the pigments in the paint.
