What does "green / yellow / red" mean in the lifestyle?
The traffic-light color system is a consent-communication shorthand borrowed from BDSM and increasingly used in mainstream lifestyle play. Green means "fully comfortable, continue"; yellow means "slow down, check in, or adjust"; red means "stop everything immediately and reconnect." It works especially well in scenes where verbal complexity is reduced (subspace, gagged scenes, intense moments) but a single word still communicates clearly. Many couples use it as their default check-in language: "Color?" — "Yellow" — pause, check, adjust.
