Bouldering grades

Arkose grades boulders with colours. Its own guide lists six levels from Yellow (introduction) to Violet (expert); a third-party table also places White below Yellow. Arkose does not publish Font equivalents, so the grades below come from a third-party conversion table.

Arkose's gyms appear to share this grading, though Arkose doesn't say so outright. All Arkose gyms and grades

From climbers' descriptions and photos of the gym's grade boards. Gyms reset and regrade often, and grades vary between setters, so treat this as a guide and check the boards when you visit.
