If you want to use an NCS® color for print or digital design, you can convert NCS® to CMYK. The perceptual NCS color values are translated into the four print colors Cyan, Magenta, Yellow and Key (Black). This makes it possible to accurately reproduce an architectural or design-based NCS color in four-color printing.
Converting NCS to CMYK is especially important for designers, architects, and agencies who want to transfer real-world color concepts into brochures, print ads, or packaging. qConv analyzes your NCS shade and automatically provides the best possible CMYK value — including color deviation and suggestions for alternative print colors.
Since the NCS system is based on human color perception and CMYK on physical inks, converting NCS to CMYK is always an approximation. Still, it enables a highly accurate visual translation for print layouts and brand materials.
How does the conversion work?
In the conversion from NCS to CMYK, qConv first transforms the NCS color coordinates into the device-independent LAB color space. These LAB values are then compared with CMYK reference profiles (such as FOGRA39 or ISO Coated v2) to determine the nearest printable color. The result is a practical CMYK value suitable for layout, proof, and offset printing.
The result is displayed in standard CMYK notation, for example cmyk(5%, 12%, 23%, 0%). qConv also shows the Delta-E value (color deviation) and related tones to ensure the best possible match.
This color conversion from NCS to CMYK is ideal for architects transferring room design colors into brochures or plans, and for graphic designers who need realistic print simulations.
Example & application
Example: The color NCS S 2050-Y10R — a warm yellow with a slightly reddish hue — roughly corresponds to cmyk(0%, 15%, 65%, 0%) in print. qConv instantly displays this NCS to CMYK conversion and offers additional options for matte, glossy, or coated paper.
Converting NCS to CMYK helps you maintain consistent color effects across media — from wall concepts to printed presentations. qConv provides accurate values, alternative suggestions, and instant previews for print production.
Tip: Use the CMYK conversion early in the design phase to ensure your colors appear natural and harmonious in print. qConv supports you with LAB-based analysis and optimized print profiles.
* Note:
qConv.com searches for the next matching color from the selected color palette. In most cases, there will be minimal or apparent color differences because there is not an exact match for every color.
The NCS® – Natural Color System – is a scientifically based color model that describes how humans perceive color. Unlike technical models such as RGB or CMYK, NCS is built on visual perception and defines colors based on their similarity to six elementary colors: white, black, yellow, red, blue, and green.
Each NCS color is identified by a systematic code that represents its visual characteristics, for example NCS S 1080-Y70R. The system provides a logical structure that allows designers, architects, and manufacturers to communicate color accurately across industries. Since April 2022, an additional 100 new colors have been added, bringing the total to 2,050 shades in the current NCS collection.
Usage
The NCS® color system is widely used in architecture, product design, and industrial manufacturing. It helps professionals create harmonies based on human color perception and enables accurate matching between digital design, paint, and materials. NCS colors are used by major paint manufacturers, design firms, and universities worldwide.
The system is also valuable for color psychology and environmental design, as it allows designers to work with perception-based contrasts and mood settings rather than purely technical color codes.
Tips for Designers & Architects
When working with NCS, focus on the relationship between hue, chromaticness, and blackness. Colors closer to white or black are ideal for subtle backgrounds, while saturated hues create striking focal points. NCS values can be easily converted to digital formats such as RGB, HEX, or CMYK using tools like qConv.
With qConv, you can search all 2,050 NCS® tones, including the 2022 additions. Simply enter “2022” in the search field to discover the newest colors.
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.
