The previous answer is right. The terminology is a bit confusing, but here is the breakdown:

HabitRPG uses "Value" as an indicator on how well you're doing on a task - high value (blue) means you're doing great on it! Low value (red) means you need to focus on it more.

Increasing "Value" means you're doing well so you need fewer rewards to motivate you.

Decreasing "Value" (like performing a bad habit, missing a daily, etc) means you need more incentive, hence more experience and gold.
