Keep color in mind!

Color is a very important aspect to consider when taking photos. A good way to make your photos "pop" is to to use complementary colors to make the subject stand out from the background. Complementary colors appear opposite each other on a color wheel chart. For example the blue background and the orange guitar. Other examples of complementary colors are purple/yellow and red/green

Another way to make your photos more interesting is to use analogous colors, or colors that are similar in hue and tone. This was a very common technique with Impressionist painters. The second example shows a dark green guitar on a light green background. This allows you to set a tone for your image depending on the colors used. Blues and greens give your image a cool tone while using reds and yellows lend a certain warmth to your photos.
