What do these colors in parenthesis mean?  And how do I get into Pole 2?

Our Level Program includes a curriculum of moves within 6 "color" routines that changes every 2 weeks to help our students practice and progress safely. We encourage students to move through the class levels at their own pace. All students can move to the next level by requesting a Level Assessment with an instructor.

A list of required moves to pass the level can be provided prior to the Level Assessment. While it is not a requirement to have attended all "color" routines, the student must be able to perform these moves comfortably and confidently in order to pass. After moving up a level, students are still welcome to review lower levels.
