Yes, there are metallic RAL colors available in the RAL color system. RAL, which stands for Reichsausschuss für Lieferbedingungen (Imperial Committee for Delivery Terms), is a color matching system that is widely used for varnish and powder coating. The RAL Classic system defines 213 basic colors, while the RAL Effect system defines 420 metallic and pearl effect colors. So within the RAL system, there are a number of metallic color options to choose from.
Overview of the RAL Color System
The RAL color system is a standardized color matching system that was originally developed in Germany in the 1920s. RAL colors are specified by a 4-digit number, except for fluorescent colors which have a 5-digit code. The 213 RAL Classic colors are the basic matte, glossy, and semi-gloss solid colors. In 2003, the RAL Effect system was introduced, which defines metallic and pearl effect paints and powder coatings. The RAL Effect colors have a 4-digit code starting with the digits 9 to 3.
The RAL system is designed to enable accurate color matching across different manufacturers and materials. Each RAL color has precise specifications for visual appearance as well as physical and chemical properties. This helps ensure consistency and quality control in the use of RAL colors across industries like architecture, construction, manufacturing, and transportation.

Popular uses include appliances, heavy equipment, agricultural equipment, commercial trucks, trailers, and more. Metallic powder coating provides durability and resistance to corrosion and abrasion while allowing customized coloring.
Consumer Goods
Within consumer products, metallic RAL colors bring attractive and modern styling to items like consumer electronics, household appliances, furniture, sporting goods, cosmetics, jewelry, and apparel. Metallic finishes help these products stand out on retail shelves and convey value, quality, and sophistication.
Architecture and Construction
On building exteriors, metallic façade cladding, roofing, window framing, and architectural accents provide aesthetic enhancement. Interior uses include doors, railings, wall paneling, and décor. Metallic coats lend buildings contemporary styling along with practical benefits like weather and corrosion resistance.
Automotive
The automotive industry utilizes metallic RAL coats for car and truck exteriors, rims, and customized accessories. Precise color matching allows OEM parts to be perfectly paired to the body paint. Metallic and pearl effect colors are popular for luxury vehicles and customized rides.
Industrial Design
Beyond purely functional equipment, metallic powders are specified by industrial designers to give designed objects like furniture, lighting, exhibits, signs, and displays enhanced decorative effects. Metallic colors in trending rose gold and copper tones are increasingly popular.
Using Metallic RAL Colors
Metallic RAL powder coats and liquid paints can be applied using standard industrial techniques like electrostatic spraying, fluidized bed, and conventional application. Curing or drying is then done thermally in a curing oven. The process results in a smooth, durable metallic finish. Using RAL Effect colors specified by their precise RAL number ensures accuracy across supply chains and assembly lines. Pantone also offers a compatible system of metallic colors.
Powder Coating
For powder coating, the metallic powder is electrostatically applied using special spray guns, then cured under heat to melt and fuse the powder into a continuous coating. The process is efficient, with nearly 100% powder overspray recoverable for reuse, and produces minimal VOCs and emissions compared to solvent-based painting.
Liquid Painting
Metallic RAL colors are also available in traditional solvent-based liquid paints. These offer the full visual effect range but involve solvents. Water-based acrylic metallic paints provide an environmentally preferred option. Paint is applied using techniques like spraying, brushing, and dipping, followed by oven or air drying. Multiple coats may be applied for better coverage and sheen.
Proper substrate preparation through cleaning and sanding enhances adhesion for both powder and liquid paints. Clear topcoating helps maintain the metallic visual effect. Strict quality control is recommended when using metallic RAL colors to achieve accurate and consistent results.
Color Matching and Accuracy
A key benefit of the RAL system is that colors can be precisely matched across suppliers and between batches. This color consistency is enabled by the technical definitions and strict tolerances prescribed by RAL specifications.
For example, RAL 9006 White Aluminum defines visual parameters like lightness value, metallic appearance, and particle size. Quantitative lab measurements of the reflective spectrum are also detailed. This standardized specification allows the color to be accurately formulated and matched across production runs and manufacturers.
However, some variation can still occur between substrates and paint types, processes, and batches. So testing and quality control is still important when using metallic RAL colors for color-critical applications like automotive manufacturing where panels from different suppliers must match seamlessly. Overall, the RAL system provides vital infrastructure for consistency.
Locator Tools and Swatch References
Various tools exist for looking up, identifying, and matching RAL colors accurately:
Official RAL Swatches
Physical RAL color fan decks contain small samples of actual colored coatings on cardstock, providing authoritative references for color identification and visual color matching. These are available for both Classic and Effect colors.
Digital RAL Charts
Online RAL color charts allow searching and browsing colors digitally using the RAL name or number code. However, on-screen colors are not completely accurate. Physical swatches should be used for final matching.
RAL Color Scanners and Apps
Devices like colorimeters and spectrophotometers can measure the spectral profile of both physical objects and color samples to identify the closest matching RAL color automatically via software. Some apps allow scanning colors using smartphones.
Lookup Tables
Conversion charts are published correlating RAL codes with other color systems like Pantone, NCS, BS 381C, and automotive manufacturer codes. This allows for cross-referencing colors across different standards and industries.
