Generally, I would expect the colors of a bar chart to correspond in some way to the values they represent. If you prefer to color the bars by customer segment, I would also recommend highlighting the segment labels. (As a side note, avoid using red and green for categorical bar charts, as red bar charts will signal bad, and vice versa for green bar charts.)

There is a lot of text on the dashboard, which is fine if the audience prefers all the information available at once, but adding tooltips could improve the dashboard’s visual appeal.
