KPI visual background colour conditional formatting based on changing value

So, I have a KPI card where the value for a department is measured against the total for the company for sickness days lost per FTE. Good is for the dept value to be below the company value. The KPI text colour works fine showing green if below company, red if above etc. But is there any way in PBI which allows me to do that for the background colour as this would make the visual stand out more? Its not a simple case of entering a static value in a conditional formatting rule as the target value with change each month.
