New API V3.0: 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 2025-10-21 up to and including 2025-11-21 (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 translate a digital screen colour into a real, perceptual tone, you can convert from RGB to NCS®. The Natural Color System is based on how humans perceive colours and is widely used in architecture and design.
The conversion from RGB to NCS analyses the red, green, and blue components and translates them into an NCS code such as NCS S 1050-Y90R.
qConv automatically calculates the nearest NCS shade by converting RGB into LAB values and matching them within the NCS reference database.
How does it work?
In the conversion from RGB to NCS, qConv first converts RGB to LAB, which reflects human colour perception, then compares it with NCS values to find the closest match (smallest ΔE difference).
The result could be NCS S 1050-Y90R or NCS S 2050-B, shown with LAB and ΔE data.
This RGB to NCS conversion is ideal for translating digital colours into physical materials for interiors, architecture, and industrial design.
Example & Application
Example: rgb(240, 60, 50) ≈ NCS S 1080-Y90R. qConv shows this RGB-NCS conversion with detailed colour metrics.
Use the RGB-to-NCS conversion to ensure consistency between digital renderings and painted surfaces.
Tip: Apply it early in your design workflow for seamless transitions from screen to reality.
* 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 RGB color model (Red, Green, Blue) is the foundation of digital color representation — from monitors and smartphones to LED lighting. It is based on additive color mixing: when all three primary colors are combined at maximum intensity, white is produced; when no light is emitted, the result is black.
Each of the three color components can take a value between 0 and 255, resulting in a total of 16,777,216 possible RGB colors that the human eye can perceive on modern displays. RGB is therefore the standard format for digital media and the basis of many color conversions, such as to HEX or CMYK.
Usage
RGB is used in all digital applications — from web design, UI/UX design and app development to video, animation, and 3D graphics. It defines color representation on light-based devices and forms the foundation of every screen display.
Design tools like Adobe Photoshop, Figma, or Sketch rely on RGB color values to define precise web colors that can later be converted into HEX or HSL formats. RGB is also the reference for modern color profiles like sRGB, Adobe RGB, or Display P3, which represent different gamuts for various display types.
Tips for Designers & Agencies
To ensure consistent appearance across devices, designers should always work with standardized profiles such as sRGB. Colors may appear slightly different on mobile devices, laptops, and monitors due to varying light output.
With qConv, you can easily convert any RGB value into print-ready CMYK or Pantone® tones. It precisely bridges the gap between digital and print color spaces while offering related harmonies, contrasts, and shades for creative exploration.
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.
