A monochromatic color scheme would be one that employs all the colors (tones, tints and shades) of a single hue. Tints are achieved by adding white to a color, while tones are achieved by adding black or gray. On the other hand, if the scheme has to be warm or cold, then different colors need to be used. Warm colors are those that are associated with heat and sunlight. It includes colors such as red, orange and yellow. Cold colors include blue, green, purple, and these colors are usually associated with cooler environments and objects, such as water, ice, sky and open spaces.
