Chart colors based on text value

[Whiskey_Gambler]

I have a chart that shows monthly revenue going back multiple years. I want each months bar on the chart to be the same color, no matter what year. So January will always be front blue and October always pumpkin orange, etc... Besides going in and changing each color by hand (which is a huge pain in the butt) is there a way to do this?

I have two columns, Gross Revenue and Month/Year in Excel 2013.
