LIST Column Formatting - using Jason

Hello All, 

I have a Risk_Value Column on my SharePoint List , the Risk value column --> will only hold 1 unique value from the 49 possible values as per the below 7*7 matrix 

Q: is there a way to format risk-value column to display color & text based on the following

• if  Risk_value is any of blue cells (blue , level 4)
• if Risk_value is within any yellow cells (Yellow , level 3) 
• if Risk_value is within any orange cells (Orange , level 2) .
• .............etc.
