Cyber Week: Get our API at a special price. Get it now. Get more detailed color conversion results - perfect for web projects, plugins, internal tools or SaaS applications. Valid from 2025-12-01 up to and including 2025-12-07 (23:59 CET)
First enter the color code to find the conversion and the best matching colors. After that, you can create palettes by clicking on and download color samples.
If you want to transfer colours from the Scandinavian NCS® system into industrial coatings or architectural paints, you can convert from NCS to RAL®. The NCS (Natural Color System) is based on human colour perception, whereas RAL is derived from real pigment and material standards. This conversion finds the RAL shade that most closely matches your NCS colour both visually and metrically.
The conversion from NCS to RAL is particularly useful for architects, interior designers and product developers who need consistent colours across materials such as walls, metals or furniture surfaces. qConv helps you find the best RAL code for your NCS value and analyse any deviations precisely.
Because NCS relies on perceived colour and RAL on physical pigment data, small differences may occur. Still, the conversion from NCS to RAL provides a reliable approximation for colour planning, material coordination and industrial design.
How does it work?
During the conversion from NCS to RAL, NCS values (e.g. S 2050-Y90R) are translated into LAB coordinates and then compared with RAL reference data. qConv uses precise ΔE calculations to determine the closest matching RAL colour.
The result is a RAL code such as RAL 3012 Beige Red or RAL 1001 Beige. qConv also displays the numerical ΔE difference and suggests alternative tones if the deviation is visible.
This colour conversion from NCS to RAL is ideal for aligning architectural designs, material suppliers and construction teams, ensuring that colour concepts are accurately realised across surfaces and textures.
Example & Application
Example: The NCS colour S 2050-Y90R corresponds approximately to RAL 3012 Beige Red. qConv instantly shows this conversion from NCS to RAL, including the ΔE difference and suggested matching RAL tones.
The conversion from NCS to RAL is especially valuable when maintaining colour harmony between digital design and production. With qConv you can analyse NCS colours, convert them into RAL values and export them as palettes for further use.
Tip: Use the NCS-RAL conversion early in your planning to ensure colour consistency in interiors, facades and furniture design. qConv helps you achieve visually coherent and technically accurate results.
* 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 RAL® color system is an internationally recognized standard for defining and communicating colors. Originating in Germany in 1927, RAL established a consistent catalog that assigns each color a unique four-digit number, such as “RAL 3020 Traffic Red.”
The classic RAL® palette includes 213 standardized colors in the RAL Classic collection. Each tone is precisely defined to ensure color consistency across materials, manufacturers, and applications. Beyond RAL Classic, there are also the RAL Design System Plus and RAL Effect lines, offering more than 2,500 colors for architecture, product design, and industrial coatings.
Usage
RAL® is widely used in architecture, construction, automotive, and industrial manufacturing to define exact color specifications for paints, coatings, and materials. It is the standard reference for designers, engineers, and production companies that require accurate and repeatable color matching worldwide.
Designers often use RAL colors when creating brand elements, interiors, and exterior coatings. The universal numbering system ensures that a chosen RAL color looks the same across all production environments.
Tips for Designers & Engineers
When selecting RAL colors, consider the surface finish — glossy, matte, or textured coatings can affect perception. Always compare samples under realistic lighting conditions. The RAL Design System Plus offers finer gradations for designers who need nuanced hues for product and interior applications.
With qConv, you can convert RAL® colors to HEX, RGB, CMYK, Pantone® or HKS® formats, making it easy to align digital and physical color specifications within your design process.
