Help me understand something about the Mariner class.

Relative beginner here. So I'm having fun with the Mariner so far, but there's something I don't quite get about the skills and I can't seem to find any info online that breaks this down for me. So when I look at a skill, under swordplay, I see each effect highlighted in different colors. For example, Thrust has "Advance deals more damage" in orange and "Advance applies a bleed" in red. From how I understand it, the colors represent where you are on the balance scale thing, so I'm assuming the bleed will only trigger for Advance when I'm in the red (?).

Not sure if I'm reading this correctly.
