While a survey found that most people dislike brown, it is a color found both in nature and in everyday surroundings. From human eyes to tree barks, brown, in all of its various shades, predominates the landscape.
The warmth of brown is associated with reliability, healing, and strength. Additionally, many find comfort in the plainness of brown because the color is considered all-natural and earthy.
As proven by the variety of colors in the flora and fauna that surround the earth, brown pairs with every color. Most often, it is used as an accessory color to one of the more primary colors and their offshoots.
