The color model is an abstract mathematical model describing an approach to represent colors by tuples of numbers such as RGB or CMYK Kaur Sahib 2015. Color space is a specific organization of colors. Each specific color model can have different color spaces. Color space is represented in a three-dimensional coordinate system. In the three dimensional systems, each color is represented by a single point. To apply color as a visual cue in computer vision applications image processing and multimedia an appropriate approach to represent the signal of color is required. Color space provides a reasonable approach to recognize order affect and effectively display the colors of the object taken into consideration. The problem's declaration and solution can be addressed by choosing a suitable color model. The knowledge about the way color signals generated and what information needed from the color signal is important during the color model selection process.
