The Google consent dialog is currently unavailable. Optional statistics and storage stay disabled without consent. If applicable, check your ad blocker and reload the page.
This policy describes the technologies we use to store or access information on your device - for example, through cookies or similar methods. This enables us to realize the purposes listed here as soon as you access or use our website.
For the sake of simplicity, we use the term 'tracker' for all technologies used. The term 'cookie' is only used when we explicitly mean cookies in the browser.
Some processing with trackers requires your consent. You can revoke this at any time - you will find the options for doing so in this policy.
We use both our own trackers ('first-party') and third-party services ('third-party'). The lifespan of individual cookies depends on the provider - some end when the browser is closed, others remain stored for longer. Details can be found below or in the privacy policies of the respective third-party providers.
How we use trackers
1. functionality
This website uses cookies and similar technologies that are necessary to provide basic functions and requested services
.
Technical cookies
Runtime:
qConv_privacy_preferences: 1 year
qConv_theme: 1 year
qConv_lang: 1 year
qConv_theme_form: 1 year
qConv_sign_in_id: 1 month
qConv_sign_in_key: 1 month
Explicitly requested features also use a login session and locally saved colours, palette names and editing drafts in the colour collector. This storage serves the requested feature and does not grant analytics or advertising consent.
Optional preferences and filters
Additional hints, search filters, sorting and menu states (for example msg1, msg2, qc_filter*, qc_from, qc_to, gradient_menu and hide_code) are stored only after consent to our own device storage. Without it, controls continue to work but additional preferences are not stored persistently. Depending on the feature, cookies last up to one year.
2. measurement of success
We use trackers to measure visitor numbers and evaluate user behavior. This enables us to continuously improve our website
.
Matomo (self-hosted)
Self-hosted Matomo browser measurement (self-hosted) starts only after you consent to qConv.com’s own content measurement. Matomo cookies remain disabled. Our visitor and conversion statistics using qc_vid additionally require consent to device storage; qc_vid expires after at most one year and qc_ref after 90 days.
Anonymous server statistics
Separately from optional browser measurement, we count successful requests for public PHP pages only as daily totals by language and page category. No IP addresses, browser data, full URLs, search terms or visitor identifiers are stored. Totals are analysed separately in our self-hosted Matomo. Local daily counters are removed after at most 180 days. Anonymous totals in Matomo are retained for long-term annual comparisons. These are server requests, including possible bots, not unique visitors. This counter also respects the objection below and transmitted Do Not Track and Global Privacy Control signals.
Object to statistics
In addition to your choices in the Google dialog, you can block optional statistics in this browser.
Your objection is stored for one year in the necessary mtm_consent_removed cookie and applies to future requests in this browser. If you delete cookies, select this option again.
Your objection could not be saved persistently. Please allow storage of the necessary privacy preference.
3. marketing

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 use an NCS® (Natural Color System) color digitally, you can convert it from NCS to HEX. This translates the perception-based NCS color into a HEX code, suitable for web design, digital renderings, or UI projects. This way, real-world color concepts can be accurately represented online.
The conversion from NCS to HEX is especially helpful for designers, architects, and brand agencies who want to digitize physical color palettes. qConv automatically calculates the exact HEX code and also displays RGB, CMYK, HSL, and LAB values for precise comparisons.
Since the NCS system is based on human perception and HEX on digital screen display, minor color deviations may occur. However, the conversion from NCS to HEX provides a reliable approximation for digital use.
How does the conversion work?
In the conversion from NCS to HEX, NCS color values are first transferred into the LAB system, then converted into RGB, and finally into HEX. qConv uses precise reference tables from the NCS color world to calculate the most accurate digital equivalent possible.
The result is a HEX code that best reproduces the perceived hue – for example, NCS S 2050-Y90R becomes #D16A6A. qConv shows these values instantly and allows you to use the color directly in digital projects.
This color conversion from NCS to HEX is ideal for synchronizing color concepts between architecture, interior design, and web design. This ensures consistent and professional color appearance across all media.
Example & Application
Example: The color NCS S 2050-Y90R corresponds approximately to the HEX value #D16A6A. qConv instantly shows this conversion from NCS to HEX – including complementary colors, visual preview, and comparison with other color systems.
The conversion from NCS to HEX is essential when matching colors between physical designs and digital media. qConv simplifies this process with automatic calculation, comparison tools, and direct export options.
Tip: Use the NCS-HEX conversion already during the design phase to ensure your colors appear consistent across devices, materials, and surfaces.
* 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 hexadecimal color system is one of the most widely used methods for representing colors in digital media. It combines the three primary colors — Red, Green, and Blue — and expresses their values using hexadecimal notation. Each color component is represented by two characters, forming a six-digit code such as #FF5733.
The first two digits represent red, the middle two green, and the last two blue. The range of each pair goes from 00 to FF, corresponding to 0–255 in decimal values. With this structure, there are a total of 16,777,216 possible hexadecimal colors, covering nearly the full visible RGB color range.
Usage
Hexadecimal color codes are the standard for web design, front-end development, and digital branding. They are supported in HTML, CSS, SVG, and nearly all design applications. HEX values are compact, easy to read, and ideal for defining precise colors in digital interfaces, animations, and style sheets.
In professional design workflows, HEX values are often used alongside RGB or HSL to ensure consistency across screens. Designers can also use HEX-to-RGB conversions to fine-tune colors for print simulations or cross-platform visual harmony.
Tips for Designers & Developers
When creating color palettes, group HEX values that share visual harmony — for instance, complementary or analogous combinations. Use lowercase HEX (e.g. #a1b2c3) for better readability and code consistency.
With qConv, you can instantly convert HEX colors into RGB, CMYK, or Pantone® equivalents, generate gradients, or explore related shades and tints. Perfect for designers and developers seeking pixel-perfect color accuracy.
To be able to save color palettes, a registration is required.
As a guest, you can collect and download colors in the color collector. Activate qConv Start for free to save color palettes permanently and manage the colors in each palette.
