Methods, apparatus and articles of manufacture for image comparison using color histograms are disclosed. Example methods disclosed herein to compare images include adjusting a color histogram associated with an input image based on a first reference color histogram associated with a first reference image to determine a first adjusted color histogram associated with the input image. Such example methods also include comparing the first adjusted color histogram and the first reference color histogram to determine whether the first reference image matches the input image. Such example methods further include displaying a version of the first reference image adjacent to a display of the input image in response to determining that the first reference image matches the input image.
