Color is an important element in design. It brings any art form to life including hand drawn illustrations and photographs. However, if you want to add a bit of drama, there are several ways to do it. One thing you can do is spot coloring where everything is black and white and you just have one color highlighted or you have a monochromatic theme.
Monochromatic colors are all the colors (tints, tones and shades) of a single hue. Monochromatic color schemes are derived from a single base hue, and extended using its shades, tones and tints (that is, a hue modified by the addition of black, gray (black + white) and white). As a result, the energy is more subtle and peaceful due to a lack of contrast of hue. Monochromatic color schemes may be considered boring unless there is diversity within the design. I put together some monochromatic photos for your enjoyment. You can really see the impact of using just one color as a theme. I hope you enjoy them as much as I did putting them together. They are truly breathtaking.
