There are just as many whites as there are reds or greens.
As a day moves from morning to night, white can shift from bright and cool to softer and warmer.
Inspired by Lisbon
The artistic cobblestones of Lisbon are made from architectural rubble after the quake of 1775. It illustrates how whites should always be intentional. Don't use white as a default because you can't choose a color. It will look unfinished. Whites can be elegant, art-gallery, complex and relaxed.
