Many times we can look at a photograph and know intuitively that the colors are off.  You may not necessarily know exactly what’s wrong if you are new to this, but if you were able to compare that photo with an identical photo of correct color balance, then you may be able to explain why.  Another more commonly used term for this concept is White Balance….  Photos with correct white balance, appeal to the eye much more than those that are not, because they express the true colors that our brain would receive from our eyes of the original scene.  A photograph with its whites truly white and its blacks truly black is one that is correctly white balanced.  All other colors in the light spectrum will be automatically set in their true state.
