Bouldering grades

Boulders are set in colour circuits marked by hold colour: Yellow is the easiest and White (or Mint, at some gyms) the hardest. Each colour covers roughly three V-grades and neighbouring colours overlap on purpose, so circuits are not a strict ladder. The ranges are read off Bouldering Project's grade chart; only Purple is also given in its text.

Level	V-scale	≈ Font
YellowAt the V0 end of the chart; may also include easier (VB) climbs.	V0	4B–4B+
Red	V0–V2	4B–5C
Green	V1–V3	5A–6A+
PurpleBouldering Project's text also gives Purple as V2–V4.	V2–V4	5B–6B+
Orange	V3–V5	5C+–6C+
Black	V4–V6	6A+–7A
Blue	V5–V7	6C–7B
Pink	V6–V8	6C+–7B+
White	V8–V10	7B–7C+
MintSome Bouldering Project gyms use White as the hardest circuit instead.	≥ V11	≥ 8A
