Conditional Formatting Percentage Axis for Thermometer Chart

I currently have a thermometer chart in Excel 2013 that I set up with percentages along the Y-Axis. The thermometers are showing spending based on a budgeted number. Currently, the project is over-budget so I have adjusted the thermometer scale to go far beyond 100%.

I would like to have the percentages past 100% show in red along the lefthand side.

Any help would be appreciated, thanks!

Thank you! This solved my problem.
