What Does Monochrome Mean?

Monochrome is a graphic design term for a color scheme built out of only one color. For example, if you wanted to create a monochromatic image with the color green, you could use any shade of green, including dark and light tones, but nothing outside of this range. When would you use this scheme? Whenever you want to evoke unity in a visual. Monochrome color palettes are actually a common practice in interior decorating!
