Choosing a color theme will give your container garden a "pulled together" look. To choose a theme, consider:
Think about the particular setting when picking out your plants and containers. The background might be other plants, patio-paving steps, fences, balcony rails, architectural siding, trim, or foundation materials. Photographing the background location of your container garden may help you when picking out coordinating containers and plants. Regardless of background, plants add a refreshing touch.
In the plant world, your palette of neutral colors broaden to include green, and brown, as well as the typically designated neutrals such as gray, black and white. These "neutrals" include both plants and architectural materials. Sometimes the background is red brick or blue siding. Take this into consideration when choosing a color scheme.
Different background colors affect how the same color looks. For example, gray, purples or greens looks different against gray siding than they do against red brick. They look different still against tan limestone or white vinyl.

Many books and references go into detail about effects of colors and color combinations in the garden and are useful to explore as you think about color.
Lighting affects how your living floral arrangement is perceived and enjoyed. Often people who work during the day take pleasure in white edged leaves and white or pastels flowers for their evening impact. The white "pops" at night. These same pale colors may appear washed out in bright light. However, in the dim light of the morning or evening, whites and pastels really show up. Deep colors are lost in darkness. When you are out and about, notice how light patterns in sun or shade affects how warm and dark colors look.
