Physical colour samples are still considered indispensable by architects, designers, and clients\u2014particularly for complex materials such as powder-coated metals\u2014despite advances in display and printing technologies. They remain essential for sensory validation and for perceiving the full visual effect of the coated product.
\nThis is closely linked to the way the human eye and touch perceive colours and materials, a process that even the most advanced digital representation can never truly replicate.<\/p>\n

\n\u2022 Colour perception is a complex psychophysical process involving the interaction between light, the object, the eye, and the brain.
\n\u2022 A key phenomenon is metamerism<\/em>, where two colours that appear identical under a given light source (e.g. a monitor) may look different under another (such as natural daylight or artificial ambient lighting). Powder-coated metals\u2014especially those with special effects such as metallic, pearlescent, textured, or wood-effect finishes\u2014are particularly subject to this phenomenon. Only a physical sample can be assessed under the real lighting conditions in which it will be used.<\/p>\n
\n\u2022 Surface structure (glossy, matte, rough) and any metallic or iridescent effect dramatically change the perception of colour.
\n\u2022 Observing a coated metal surface from different angles can make colours appear lighter or darker due to the reflectance of metallic particles. Digital screens cannot accurately or consistently simulate this dynamic variation in gloss and colour shift.<\/p>\n
\n\u2022 The final decision on a material is based not only on sight. Touch provides essential information about texture, perceived quality, and the \u201cfeel\u201d of the material\u2014fundamental elements in design and architecture.
\n\u2022 A physical sample allows you to perceive roughness, smoothness, and coating thickness, aspects that a photograph or 3D rendering cannot convey.<\/p>\n\n
\n\u2022 Complex decisions:<\/strong> integrating visual perception (colour, gloss, metamerism) with tactile perception (texture, materiality).
\n\u2022 Unambiguous communication:<\/strong> ensuring that clients, designers, suppliers, and manufacturers share an objective, non-ambiguous reference\u2014extremely valuable should any dispute arise regarding colour selection.<\/p>\n","protected":false},"excerpt":{"rendered":"
