Workaround Different Bar Colours for simple waterfall

Hi PBI_22 

All free waterfall charts allow you to assign a single uniform color for the start and end points, while using different colors for the changes in between.

Additionally, you can add markers for increases and decreases using colors of your choice.
(I recommend using a combination of blue and red since green and red are colors that colorblind individuals, who make up about 10% of the male population, often cannot distinguish.)

If you want the start and end points to have different colors, you can either:

Use a paid chart option, for example:

 OR code your chart using Deneb, as shown in the link I’m attaching.

From an effective visualization perspective, I wouldn’t recommend adding another color. Adding extra colors increases the cognitive load for interpretation, especially since waterfall charts are already complex for most people to understand and read.

The logical goal of a waterfall chart is to highlight the “extremes” (start and end points) and what happened between them.
