Colors set in the HUD editor take precedence over those in the color conditions. Verify that you don't have colors set in the HUD editor.
Instead of cnt_hands, you might want to use the denominator of the stat expression, i.e., the opportunities for the action. For example, the stat expression for "Fold to PF 3 Bet" is:
(cnt_p_3bet_def_action_fold / cnt_p_3bet_def_opp) * 100
So you could use
cnt_p_3bet_def_opp < 200
With this change, it might be better to use a number smaller than 200. 100 will give you +-10% accuracy with 95% confidence in the worst case (i.e., which is when a player does an action 50% of the time.)
You can, with some effort, duplicate Holdem Manager's dimming function in this way. HM's dimming levels are set at something like 20, 40, 100, 200, and 400 opportunities.
