a. This is Multi-Hue color map which represents diverging color sequence. I have used a range of colors from green to purple. These colors represent the five ranks in the dataset. These have a different range of colors and is appropriate to represent multi-hue color map.
b. Single-Hue of different shades of red is used to represent the ranks in the dataset. I have chosen red because it gave a clear view of different levels of red color. Also, it looked attractive.
