You would need to do that by adding colour conditions to the stats themselves rather than via the Hud.
For example:
Go to Configure > Statistics and select the stat you're interested in.
Click the Colors tab.
Say we're looking at PFR, we can add a Condition Expression like this:
cnt_pfr_opp > 100 AND #PFR# < 10
Pick a colour and tick the 'HUD' option, and click Save.
Click New and repeat for each colour range.
