Stability and a solid foundation is the message that emanates from the color brown. This color relates to things that are natural and simple. Brown is thought to be dull, but is reliable and wholesome. Although frugal and stingy, brown is a color of safety and quiet confidence; warm and reassuring. Sadly, brown is among the least favourite colors, but conveys honesty and sincerity. On its own, brown seems unsophisticated, but when combined with others can become quite elegant.
Grey is considered to be an unemotional, detatched color seeking to avoid attention. It conveys gloom and depression. Very conservative, grey has a stabilizing effect as it is very neutral, but can also conjure up feelings of frustration. Grey is linked with maturity and protection, being reliable and practical. Grey would not be considered a glamorous colour, yet is still elegant.

It absorbs a huge amount of energy from white sunlight. It absorbs the waves in the red frequencies, and the blue, and the violet, orange, and yellow frequencies.
But it doesn't do a great job of absorbing light in the green frequencies. So the green frequencies are reflected instead! And that's why plants look green. The common theme here is that color is not something that exists in objects. We perceive things to be a certain color because of the way our eyes sense the various frequencies of light reflected off of them. Objects that appear red do not contain the color red. They only contain the molecules that affect the visible light waves so that only red is reflected.
Therefore, color is the perception of a visible light wave's frequency. White light is a combination of all the frequencies of visible light. When white light strikes an object, each individual frequency of light is transmitted, reflected, or absorbed, depending on the properties of the surface molecules. If all frequencies are absorbed by the object, then it appears black. If all frequencies are reflected, then it appears white. Selective absorption describes how some frequencies of light are absorbed while others are reflected. This results in the appearance of color.
Product description
Pigments are natural or man-made chemicals that give color to objects through selective absorption. While we often describe objects as 'being' a certain color, the truth is that color is only our perception of the light frequencies reflected off of objects.
