Error Prevention in Large Projects: Eliminating Misunderstandings in Color Codes

A Costly Nightmare

A painting company receives an order for an office building with 40 rooms. RAL 7035 (Light Grey) is planned for the hallways, and NCS S 1502-Y50R (a warm grey-beige) for the offices. Due to a transmission error, RAL 7035 is also ordered for the offices. The result: 600 m² of wall surface in the wrong color. Costs for material and rework: over 15,000 €.

The Most Common Sources of Error

Confusion of color systems: RAL, NCS, Brillux, Caparol – each system has its own codes. A mix-up can happen quickly.

Illegible handwriting: "7035" or "7035"? A poorly written code can have fatal consequences.

Oral transmission: "Tell the paint dealer it should be the same gray as the last project" – what could go wrong there?

Missing versioning: When the customer changes the color tone and not all parties involved are informed.

How Digital Project History Protects

A central, digital project documentation prevents these errors:

Exact color storage: Each color code is stored with its system (RAL/NCS), hex value, and description.

Photo documentation: Color samples are photographed and assigned to the project.

Change log: Every color change is documented with date and reason.

Team access: All involved parties see the same, current information.

Checklist for Error-Free Color Projects

Always record the color system in writing (RAL, NCS, manufacturer code)

Save a digital photo of the color sample in the project

Update changes immediately in the system

Before ordering: obtain digital approval from the customer

Conclusion

Color errors in large projects are expensive and avoidable. Digital project history with exact color storage is the best insurance against costly misunderstandings.
