We use blue for guestroom surfaces, yellow for sinks and chrome, and red strictly for toilet touchpoints — keeps microbes in their lane and makes coaching a 14-person shift easier on sold-out Saturdays. Do your properties stick to this code or swap green in for glass and mirrors?
We do swap in green for glass/mirrors — ‘green = glass’ — and added small icons on the caddy slots for color-blind teammates; it’s traffic lights for housekeeping. One tweak that cut cross-overs was par-leveling cloth bins on each floor so nobody raids the wrong color mid-round. Do you color-match your spray bottle labels as well?
