CMYK color profile
Short description
The CMYK color model (Cyan, Magenta, Yellow, Key/Black) is the standard color space for professional four-color printing. It describes how colors are created by mixing printing inks on physical material - usually paper. In contrast to RGB, which adds light colors, CMYK works subtractively: the more color is applied, the less light is reflected - and the darker the result appears.
Each of the four colors can have a value between 0% and 100%. A high percentage value stands for high color coverage in the print. By combining these values, several trillion CMYK color tones can be generated - however, the displayable color gamut is lower than that of RGB, which is why conversions can lead to visible color deviations.
Use
The CMYK color system is the industry standard in printing - from magazines, catalogs and packaging to corporate designs. Every professional print shop works with CMYK color profiles (e.g. ISO Coated v2, FOGRA39) to ensure consistent and accurate color results. Designers should therefore convert their RGB or HEX colors to CMYK before approving them for printing in order to minimize colour deviations.
In digital design programs such as Adobe Photoshop, Illustrator or Affinity Designer, the CMYK color space can be selected directly as a working profile. This allows printing colors to be simulated exactly and checked visually at an early stage.Tips for designers & agencies
When converting screen colors (RGB/HEX) to CMYK, note that particularly bright blue, green and neon tones appear duller in print. A soft proof preview helps to assess the color appearance. For corporate designs, use CMYK color values from verified brand guidelines or Pantone references to achieve consistent print results.
When working with qConv, you can convert any digital color to exact CMYK values in seconds, compare color deviations and even generate matching alternative palettes.Sikkens 4041 Color System
Short Description
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.
