Colors fall into three general categories:

a) Warm
b) Cool
c) Neutral

The way we mix those colors along with attention to value, can enhance the use of color in design and communicate explicit messages.

a):  Warm colors in design convey excitement and energy:  red, orange, and yellow.

b)  Cool colors are calming and relaxing:  blue, green, and violet.

c)  Neutral colors are unifying and help us focus better:  white, black, and gray.

Different spaces within a home or office may need different colors depending on the purpose of the space.  Design colors in the office can be essential to the image and mood that is created thus helping productivity and enriching aesthetics.
