Restoring the actual colors in images also called color constancy technique is still an open area of research in digital image processing. Many techniques has been proposed so far in order to improve the accuracy of the color constancy techniques further. This paper has presented a comparison between some well known latest color constancy techniques. The review has clearly shown that each technique has its own benefits and limitations as well. However none is promising in every case of vision processing. The comparisons have clearly shown that the ColorCat based constancy has better results over each technique.
