The Sikkens 4041 color system is a professional color collection by the Dutch manufacturer AkzoNobel, developed for precise color design in architecture, interior design, and coating technology. With over 2,000 carefully defined shades, it offers a wide range — from neutral greys to vibrant accent colors. Each shade is based on exact LAB measurements and structured systematically by hue, lightness, and saturation.
Sikkens 4041 is known for its exceptional color depth, high repeatability, and stability under different lighting conditions. The system was designed to reproduce colors consistently across various materials and surfaces — whether wall paints, lacquers, or glazes — making it one of the most accurate color systems in professional use.
Usage
The Sikkens 4041 system is used globally in architecture, interior design, painting, and design studios. It serves as a reliable standard for high-quality surface coatings that meet the highest demands for aesthetics and durability. In combination with Sikkens Alpha, Rubbol, or Cetol products, it enables long-lasting color concepts for both interior and exterior applications.
Thanks to its structured color organization, Sikkens 4041 is also ideal for digital color planning. With tools like qConv, Sikkens 4041 color values can be accurately converted to other systems such as RAL, NCS, or Pantone® to ensure color consistency across media and production processes.
Tips for Designers & Agencies
The Sikkens 4041 color system is perfect for creating precisely coordinated, harmonious color spaces. It provides clear gradations ideal for corporate design, spatial concepts, and material combinations. The categorization into color families helps designers build harmonious palettes systematically.
With qConv, you can convert Sikkens 4041 colors online, calculate complementary and accent colors, and export LAB or RGB values for digital use. This allows you to translate real-world colors precisely into digital media — without quality loss and with maximum color accuracy.
The DB Iron Mica Colors (Deutsche Bahn tones) are an industrial color system originally developed for corrosion protection and coating of steel structures in the railway sector. They are characterized by their metallic mica component, which provides exceptional weather resistance and durability. The tones feature a slightly textured, shimmering surface that reflects light differently depending on the viewing angle.
The system includes a range of standardized shades, such as DB 601 (Iron Mica Gray), DB 702 (Gray Iron Mica), and DB 703 (Dark Iron Mica Gray). These colors are defined by technical standards and are widely used as long-lasting protective coatings in architecture, industry, and metal construction.
Usage
DB Iron Mica colors are primarily used in metal and steel construction, architecture, and for façade and bridge coatings. Due to their high mica content, they offer excellent corrosion resistance, even under extreme weather conditions. They are particularly popular for outdoor use, giving surfaces a refined texture and a high-quality, technical appearance.
In contemporary architecture, DB colors are increasingly used for aluminum profiles, window frames, and metal façades. Manufacturers such as Schüco and SIEGENIA offer coatings based on these tones to combine design, functionality, and longevity.
Tips for Designers & Agencies
DB Iron Mica colors are ideal when a robust metallic look with understated elegance is desired. Pay attention to the effect of the mica pigment: depending on the light source and viewing angle, the tone may appear lighter or darker. For digital visualization, the metallic effect can only be approximated — a physical sample is therefore essential.
With qConv, DB colors can be quickly compared to systems like RAL, NCS, or Pantone to find suitable alternative shades or complementary accent colors. This ensures that designs are consistent and realistic — from visualization to the finished metal surface.
