The burnt sienna color is an earth color. During the Renaissance, there was a state of the same name. I guess the land of this place looked like this color.
It is rare for a painter to have one true color to their name, but you can find Burnt Sienna. It is very unique in its application, with few colors being so receptive to different strategies. Layers of paint are encouraged with Burnt Sienna, but if you want one color that can do it all, you found your match!
It is actually much easier to paint an entire wall in pastel shades instead of picking out several different colors to cover the entire area.
