Creating Bar Graph with different bar colors

I am trying to create a bar graph with different colors for the bar using the attached data. x-axis should be the (Group) and the bar height as the y-axis (Percentage Failure). Any quick help will be deeply appreciated.

Thanks for the support

There are some examples of how to do this here: Bar Graph Ref!

What rule do you have for coloring the bars? Different bar height ranges are different colors? Bars are all unique colors? What???
