Contrast in Graphed Values in Bar Charts

Our team would like to have more customizable contrast when graphing values in a bar chart. When graphing in Domo, regardless of value, the bars look very similar without a distinct delineation between the bars/values. When graphing in excel you see much more contrast in the bars. We have worked with Domo support and the only solution was working with the value scale and there was not a noticeable difference even when adjusting the value scale.
