The RAL P1 Plastic Colour Sample Set is a professional material-specific colour reference for plastic product design, plastics manufacturing and technical colour communication. It contains 100 selected RAL CLASSIC colours as polypropylene plastic plates in a protective case and is designed for industrial manufacturing, product development, industrial design, architecture, interiors, engineering, advertising and professional colour specification for plastic materials.
RAL CLASSIC is one of the most recognised colour systems for industrial and architectural colour communication. However, colour behaves differently in plastic than it does in paint, coating, paper or digital media. Material thickness, surface texture, opacity, pigment behaviour, light transmission and production method can all influence the final perception of colour. The RAL P1 set addresses this challenge by translating important RAL CLASSIC colours into real polypropylene material samples.
The set contains the 100 most frequently requested and most important RAL CLASSIC colours for plastic applications. These colours have been selected and arranged in a visually logical order according to colour lines, with a strong representation of relevant yellow and grey tones. The collection gives designers, plastics processors and manufacturers a practical reference for transferring familiar RAL CLASSIC colour standards into plastic product contexts.
Each RAL P1 colour plate is made from polypropylene, a widely used plastic material found in many industrial and consumer products. Polypropylene was chosen because it offers balanced technical properties, versatile processing possibilities, good cost-performance value and compatibility with a broad range of pigments. This makes it a practical material basis for communicating colour in plastics development and production.
Each plastic colour sample measures 10.5 × 14.8 × 0.3 cm. The A6 format provides a significantly larger and more realistic surface for evaluating colour than small chips or fan-deck swatches. A larger plastic plate helps users judge colour depth, saturation, surface effect, light behaviour and material impression more accurately in relation to real product applications.
A key feature of RAL P1 is the three-level thickness structure. Each plate includes sample areas of 0.3 cm, 0.2 cm and 0.1 cm thickness. This allows users to assess how the same colour behaves in different material thicknesses and opacity levels. In plastics, colour can appear stronger, softer, lighter or more saturated depending on wall thickness and light interaction. RAL P1 makes these effects visible in a direct physical format.
Each plate also includes three different surface textures: high-gloss polished, VDI 24 and VDI 42. These textures help users understand how roughness and surface finish influence colour perception. A colour may appear brighter and more brilliant on a polished surface, more subdued on a textured surface or more technical on a rougher surface. This makes the set highly relevant for realistic product design and plastics engineering decisions.
The RAL P1 plates include reflectance curve information, absolute values and the divergence from the RAL original sample. This technical data supports not only visual assessment but also professional colour communication and quality-control workflows. It helps bridge the gap between design intention, masterbatch development, plastics processing and final product approval.
For industrial manufacturing, RAL P1 supports colour decisions for plastic housings, components, panels, trims, covers, fixtures, tools, equipment, appliances, electronics, furniture parts and technical products. Physical polypropylene samples provide a more accurate material reference than coated paper or paint swatches when the final product will be produced in plastic.
For product design and industrial design, the set helps teams develop colour concepts for consumer goods, hardware, lifestyle products, packaging components, accessories, toys, display systems, advertising objects and plastic-based product families. Designers can evaluate colour and surface together, making it easier to understand the emotional, functional and material character of a shade.
For plastics processors, compounders, moulders and masterbatch producers, RAL P1 provides a practical starting point for translating RAL CLASSIC colours into plastic. The previous need to reinterpret coated RAL paint samples for plastic production could be time-consuming and costly. RAL P1 helps reduce this gap by offering binding plastic standards that are closer to the material reality of production.
For advertising, branding and visual communication, RAL P1 is useful when brand colours or design colours need to be transferred into physical plastic objects. Signage components, display systems, retail fixtures, promotional products, packaging elements and branded hard goods all require material-specific colour decisions that cannot be made accurately through screen colour or paper references alone.
For architecture and interior design, the set is relevant when plastic elements are used in interiors, technical fittings, panels, lighting components, furniture details, signage, displays or decorative surfaces. The A6 plates can be compared with metal, textile, glass, wood, coatings, laminates and other material samples, helping teams develop more confident colour and material combinations.
The protective case keeps all 100 plastic colour samples organised and ready for professional use. Each colour sample is also supplied in a protective sleeve, helping protect the plate from dust, dirt, scratches, fingerprints and external influences. For studios, laboratories, production teams and client-facing environments, this protection supports long-term usability.
The RAL P1 set is also a strong companion to RAL CLASSIC colour fans and primary standards. A colour may first be selected using a RAL K5, K7 or primary standard reference, then checked with RAL P1 to understand how it behaves in polypropylene. This creates a clearer bridge between general colour specification and plastic material execution.
All RAL P1 plastic colours are also available as individual plates. This is useful when a specific colour is frequently used, sent to suppliers, included in project documentation or required at multiple development locations. Instead of replacing the entire set, individual plates can be reordered when needed.
The RAL P1 set should be understood as a professional material-specific colour standard for plastics. For final production approval, additional application-specific trials may still be required, because final colour can be influenced by resin, additives, pigment concentration, masterbatch formulation, mould texture, processing method, wall thickness, lighting and viewing conditions. RAL P1 provides a binding and highly practical reference, but final validation should always reflect the exact production context.
For professionals working with RAL CLASSIC colours in plastic materials, the RAL P1 Plastic Colour Sample Set is an essential tool. It supports more accurate colour decisions, clearer plastics specification, better supplier communication and more reliable quality control across product design, industrial production and material development.
