Dana, There are lesser quality paints that will dry differently (cause the light to reflect differently and make the color look lighter or darker)if applied at different shear rates. In other words, some paints will dry differently if rolled as opposed to brushed. Typically, corners are brushed and the rest of the wall is rolled. There are higher quality paints formulated to minimize this effect that will "level" or flow more smoothly irregardless of shear, and will dry to produce the same smooth, even coat.
