Green / Yellow / Red
Also called: Traffic Light System, Color System
A consent communication shorthand — borrowed from BDSM and increasingly used in mainstream lifestyle play — where partners use color words to signal their state. Green means "fully comfortable, continue"; yellow means "slow down, check in, or adjust"; red means "stop everything immediately and reconnect". Especially valuable in scenes where verbal complexity is reduced (subspace, gagged scenes, intense moments) but a single word still works.
The traffic-light system is the most widely adopted safeword convention in BDSM and increasingly the default in lifestyle play space as well. Wikipedia's article on safewords describes it as the most common system in use and notes that organised play events frequently require it precisely because everyone arrives knowing the protocol without explanation: red stops the scene immediately, yellow signals to slow down or check in, green confirms full enthusiasm.
The reason it has displaced single-word safewords (the old “banana” or “pineapple”) at most public events is that it gives a graduated vocabulary rather than a binary kill switch. A bottom can communicate “keep going but ease up on the intensity” without breaking the scene, and a top can ask “colour?” at intervals to get a one-syllable status check that does not pull either party out of headspace. In scenes where verbal complexity is impaired by gags, sub-space, sensory deprivation, or sheer intensity, a single colour word remains accessible long after sentences have stopped working.
Many groups pair the traffic-light system with a non-verbal backup: dropping a held object, three rapid taps, or a designated hand squeeze, all meaning the equivalent of red. The colour vocabulary has also leaked out of strict BDSM contexts into vanilla swing and lifestyle play, where couples use it for the same reason it works in dungeons, that one syllable is easier to say than a full request when something needs to change in the next two seconds.

Related Terms
- Safe Word — A pre-agreed word that any participant can use to immediately stop or pause a sexual encounter, regardless of context. Borrowed from BDSM practice; widely adopted in lifestyle play, especially for first-time encounters or when negotiating new boundaries.
- Consent — Voluntary, informed, ongoing agreement to a specific sexual or play activity. Consent must be freely given, can be withdrawn at any moment, and applies only to the act explicitly negotiated. Non-monogamous communities place consent at the centre of every encounter — the difference between swinging and infidelity is consent at every level.
- Check-In — A deliberate pause during or after a scene to confirm everyone is comfortable, present, and still on the same page. Check-ins can be verbal ("colour?", "still good?") or non-verbal (eye contact, hand squeeze). Standard practice for first-time encounters and kink-heavy play.
