Color Image Histograms
quoted from Digital Image Processing : An algorithmic Introduction Using Java by Burger and Burge (2008) page : 47-49
When referring to histograms of color images, typically what is meant is a histogram of the image intensity ( liminance) or of the individual color channels.
Luminance histograms and component histograms both provide useful information about the lighting, contrast, dynamic range, and saturation effects relative to the individual components.'
