The British Standard BS 381C colour chart offers a well-established set of colours traditionally used in industrial & public sector applications, and it’s an excellent option for specialised office environments. Whether you’re looking to match your aluminium partitioning framework to existing elements such as signage, or simply want to add an industrial flair to your office design, BS 381C offers a robust range of colour options. This colour system ensures that our partitioning systems & skirting can be customised to fit even the most unique requirements, while maintaining a polished, uniform look throughout your workspace.

notice

While we’ve done our best to represent BS 381C colours accurately, the way they appear on your screen may vary depending on your display settings and lighting. We recommend referring to a physical BS colour chart or sample for the most accurate colour match.
