Of course everyone has their favorite color, but combining colors can be a challenge. Color is subjective and how people respond to it depends on several things, but none more important than light. Light is essential and the amount of light available in a landscape will open up the possible plants dramatically. Landscapes, or gardens, represent a composition; and one of the key ideas of composition – framing – will help hold the landscape together.
The key principles of combining colors are analogous, complimentary and contrasting. Your conditions will dictate certain color palettes. For example deep shade can reduce the variety of plants that will be available in the landscape design. However, when you consider how many shades of colors exist you will never run out of options for finding the perfect color combination for your landscape.
