The color constancy has potential to displace the precise colors in provided picture by considering the effect of color light source. Many color constancy techniques has been suggested until now to increase the color constancy precision fee further. In existing literature number this type of technique is available which acts optimistically generally in most case. Though the color cat indicates efficient benefits over available techniques, nonetheless it still is suffering from the problem of uneven illuminate and poor brightness. Thus to cope with this problem in that paper a brand novel incorporated color cat approach is proposed in that dissertation. The brand novel strategy has applied color normalization and saturation weighting as post handling of color cat to reduce the effect of uneven illuminate and poor brightness. The entire benefits indicate the potency of the proposed approach.
