It is the only trait that isn't explicitly mentioned by the Ball game. However, it is mentioned pretty much everywhere else in regards to Frisk/Chara. In the save points, Chara's speech at the end, and Asriel himself says it's your defining trait that got you so far.

It is also possible that Frisk and Chara could be considered to have different traits. Frisk's initial win condition for Ball game lists each of the previous virtues, implying a mastery of them all. Examining the goal as Chara simply colors the word 'hole' in red, perhaps an indication of how they are empty inside and possess no virtues besides determination to reach their goal.

I'd like to just clear things by saying that I do believe the red soul trait is Determination. Each soul likely has a little bit of each trait, with the dominant one defining the color/abilities. This is why DT can be extracted from the other human SOULs.

Asgore saying they have the same look in their eyes can easily be explained by the fact that both Chara and Frisk have the same colored soul. That being said, it's still an interesting thought.
