First method: mutes grey by using more steps (DO EVEN #), ensuring a smoother transition.
Second method: eliminates grey by making the field discrete and manually selecting colors.
Second method limitations: it may not work as expected if
1. The x-axis size is unknown
2. New x-axis values are added
3. There are too many values - as the size of your custom color palette must match the number of x-axis values to avoid manually assigning colors
