Choosing Between RAL 6007 Bottle Green and RAL 5013 Cobalt Blue Containers
The curious psychology of container colours: how the right shade of green pacifies planning officers, while blue commands respect on commercial yards.
Key Takeaways for East Anglian Site Managers
- RAL 6007 Bottle Green is the undisputed champion for rural East Anglia, practically vanishing against English hawthorn and field hedges.
- RAL 5013 Cobalt Blue projects corporate authority and maritime heritage, hiding tyre scuffs and tarmac grime on logistics yards.
- Both colours are baked-on marine two-pack polyurethane enamel over zinc primer, engineered to shrug off North Sea salt spray for 20+ years.
- Green units command a £100–£150 second-hand price premium amongst private smallholders and equestrian buyers in Suffolk and Norfolk.
1. The Rory Sutherland Rule of Container Aesthetics
Rory Sutherland frequently notes that how something is perceived visually often matters far more than its objective utility. Consider a shipping container: physically, it is a steel box made of Corten anti-corrosive alloy, measuring exactly 8 feet wide and 8 feet 6 inches high.
Yet paint that exact same box bright lemon yellow, and neighbours will complain to the parish council within forty-eight hours that an industrial eyesore has landed in the village. Paint it RAL 6007 Bottle Green, tuck it against a hedgerow, and those same neighbours will walk their labradors past it for five years without ever noticing it exists.
At Shipping Container Consultants Ltd, our new One-Trip fleet on the Felixstowe sidings is stocked strictly in Great Britain's two benchmark industrial specifications: RAL 6007 Bottle Green and RAL 5013 Cobalt Blue. Here is how to choose between them.
2. RAL 6007 Bottle Green: The Stealth Operator
For farms, riding stables, golf courses, garden centres, and private domestic properties bordering rural land, RAL 6007 Bottle Green is by far our most popular choice across East Anglia, accounting for over 70% of non-industrial orders.
RAL 6007 is a deep, muted, organic green with subtle dark undertones. Rather than drawing the eye like bright emerald or lime, Bottle Green mimics the natural canopy of East Anglian hawthorn hedges, mature oaks, and Scots pine belts. From 50 metres away across an open paddock, a green container recedes into the landscape, looking like an intentional, permanent outbuilding rather than an industrial shipping box.
If your parcel of land sits within an Area of Outstanding Natural Beauty (AONB) — such as the Suffolk Coast & Heaths or Dedham Vale — or is in close proximity to public footpaths, local planning officers and parish councils are vastly more inclined to approve or overlook temporary demountable storage if it is specified in subdued RAL 6007 Bottle Green.
3. RAL 5013 Cobalt Blue: The Industrial Workhorse
In contrast to rural greenery, RAL 5013 Cobalt Blue is the defining colour of commercial maritime enterprise. It is a bold, dignified navy tone with deep rich saturation that looks immaculate against concrete yards, tarmac loading bays, and modern steel-clad industrial buildings.
For logistics depots in Felixstowe, civil engineering plant yards in Ipswich, builders merchants in Norwich, and scaffolding yards across Colchester, RAL 5013 projects an aura of corporate cleanliness and security. It looks authoritative, hides everyday rubber scuffs and diesel soot well, and harmonises with corporate fleet liveries.
4. Three-Layer Marine Enamel vs Cheap DIY Re-Sprays
Beware the budget container reseller offering 'freshly painted' used boxes. Often, that means an unvetted operator in a field spraying cheap household gloss over active rust scale. Within nine months of East Anglian winter frost and rain, that paint peels off in sheets like sunburned skin.
Our One-Trip units leave the factory with an immaculate 3-stage maritime coating: shot-blasted Corten steel, a 30-micron zinc-rich primer, a 40-micron intermediate epoxy barrier, and a baked top-coat of two-pack polyurethane marine enamel. It is engineered to cross international oceans; sitting in a Suffolk farmyard is a holiday by comparison.
| Attribute | RAL 6007 Bottle Green | RAL 5013 Cobalt Blue |
|---|---|---|
| Primary Setting | Farms, stables, estates, domestic gardens | Commercial yards, depots, ports, construction |
| Visual Impact | Subtle camouflage, blends into hedgerows | Crisp, authoritative, clean commercial look |
| Planning Suitability | Highest approval rate in rural/AONB settings | Ideal for B1/B2/B8 industrial zoning |
| Dirt & Dust Concealment | Excellent against field dust, mud & algae | Very good against tarmac grit & machinery soot |

5. The Secondary Market Liquidity Factor
A shipping container is an asset that holds its residual value remarkably well. Unlike a timber shed that rots or a galvanised tin barn that rusts through, an ISO Corten container maintains strong liquidity.
If you plan to use your container for a 3-to-5-year temporary project and then resell it onto the local market, RAL 6007 Bottle Green typically has the widest pool of private buyers in East Anglia. Smallholders, equestrian centres, and self-builders in Suffolk and Norfolk actively search for second-hand green One-Trip units, often paying within 75% of their original purchase cost.
Conversely, commercial enterprises and plant hire companies in larger regional hubs prefer RAL 5013 blue units for fleet consistency.
6. Summary Recommendation for East Anglian Buyers
Our straightforward rule of thumb is simple:
• If your container will sit on grass, gravel, near trees, or behind an agricultural barn: Choose RAL 6007 Bottle Green.
• If your container will sit on tarmac, concrete, in a commercial yard, or alongside industrial units: Choose RAL 5013 Cobalt Blue.
