Orange vs Yellow – Which should you choose? 🚧🤔
It’s the age-old question in the trade: Orange or Yellow? While both keep you visible, the "correct" choice usually depends on where you’re standing.
The Comparison:
🟡 Fluorescent Yellow (The All-Rounder)
Best For: General construction, warehousing, and roadworks.
Why? It is the brightest colour to the human eye under most light conditions.
The Catch: It can occasionally blend into bright green foliage or rural backgrounds in the height of summer.
🟠 Fluorescent Orange (The Specialist)
Best For: Rail (Network Rail), sea fog environments, and quarrying.
Why? Orange provides the strongest contrast against "busy" backgrounds like green fields or grey stone.
The Law: If you are working on or near the tracks in the UK, RIS-3279-TOM standards mean Orange is your only legal option to avoid confusion with signal flags.
The Verdict: Working on a standard building site? Yellow is usually the go-to.
Working on the railways or in forestry? Orange is essential.
