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.

|---|---|---|
| WhiteOnly in the third-party table; Arkose's own guide starts at Yellow | 3 | VB+ |
| Yellow | 4–4+ | V0−–V0+ |
