Color standard systems: Pantone, RAL, CMYK, RGB, HEX
Which system to choose for a specific task
Before arguing about the 'correct' brand color, it is worth separating the systems by purpose — they are not competitors, but tools for different productions.
| Task | System | Why exactly this one |
|---|---|---|
| Logo, brand style (master file) | Pantone | Fixes the physical paint standard, identical in any printing house in the world |
| Packaging, offset printing | CMYK + Pantone Color Bridge | Provides a recipe for four colors with an official link to the Pantone number |
| Website, app, social networks | RGB / HEX | The only format that the screen can display directly |
| Industrial painting (metal, facades, cars) | RAL or NCS | A physical color wheel sample that the contractor checks visually on site |
The mistake that almost all startups make: they approve the brand color in HEX and then try to match it to Pantone for printing 'by eye.' The correct order is the reverse — first the Pantone is fixed as a standard, from which CMYK-, RGB-, and HEX-versions are derived with the understanding that they will look slightly different.
Why RGB on screen and CMYK on paper are different worlds
RGB works through pixel glow and covers much more shades than four printing inks can provide. The problem is not with the printer quality, but with physics: CMYK has a smaller color gamut, and part of the RGB spectrum simply does not fit there.
Blue, green, and red hues suffer the most during conversion — precisely the colors that are most often chosen for logos, because they 'pop' on the screen. Pure red RGB (255, 0, 0) in print turns into a dark, brick-like shade with a noticeable difference ΔE 6–10 — the human eye can see such deviation without any instrument. Bright neon green or electric blue suffer even more: in CMYK they become murkier and darker, because ink of such brightness does not physically exist.
Pantone Color Bridge: the bridge between the standard and print
A regular Pantone swatch is a sample of mixed paint applied to paper, and it is not directly tied to a CMYK recipe. Color Bridge solves exactly this problem: for all 2 359 base Pantone colors, it publishes an official CMYK equivalent that is as close as possible to the original when printed via offset printing.
This is critical for the brand book: the designer specifies Pantone for the standard and the Color Bridge CMYK value for layouts that are printed without special ink. Without Color Bridge, the printing house guesses the CMYK 'by eye' through a profile, and the result may differ from batch to batch — whereas Pantone controls physical samples of each batch of ink, so Pantone 286 C looks the same in New York and in Tokyo, but a CMYK imitation of this color does not, as it depends on the specific press, paper, and machine settings.
ICC profile and soft proofing: how to see the color before printing
An ICC profile is a description file that indicates how a specific device or paper interprets color: a monitor, a printer, or a type of sheet coating. Without a profile, the printing program does not know what physical shade should result from the digital CMYK values, and it substitutes averaged settings, which often distort the color more than the RGB to CMYK conversion itself.
- FOGRA39 (ISO Coated v2) — a standard for coated paper, used in Europe for glossy catalogs and packaging
- FOGRA47 — a standard for uncoated paper, used for kraft packaging and office printing
- An incorrectly selected profile shifts color just as noticeably as an error in the RGB → CMYK conversion
Soft proofing — a practical function in Adobe Photoshop and Illustrator (View menu → Proof Colors), which shows on the screen how the layout will look after printing, taking into account the selected profile and paper color. This is the only way to see the problem before the run has already gone to the printer, rather than after a complaint call from the client.
RAL and NCS: two different languages for industrial color
Both systems compete with Pantone in the field of industrial coloring, but describe color fundamentally differently, and confusing them is a gross error when compiling a technical specification for a contractor.
| Parameter | RAL | NCS |
|---|---|---|
| Principle | A catalog of fixed sample numbers | A perception formula based on six elementary colors: white, black, red, yellow, green, blue |
| Palette volume | 216 colors in RAL Classic | Systematizes the entire color space, not a final list |
| Geography of application | Germany and the DACH region industry | Standard for buildings in Sweden, Norway, Spain, South Africa |
| Connection to CMYK | No official equivalent — any CMYK version of RAL is approximate | No direct translation to CMYK either, the system is tailored for paints and coatings |
There is no direct conversion between RAL and NCS — this is not a lookup table, but two different ways of thinking about color, and one can only be translated into the other through physical sample comparison. If a brand works with European facade coloring or architecture, it makes sense to ask the contractor right away what system they are used to working with, rather than imposing Pantone, for which industrial paint is often simply not produced.
What else is important to consider in practice
Pantone recommends updating physical palette fans every 6–18 months — paper and pigments in samples fade, and an old fan begins to lie about the true color. Saving on a new edition means risking the brand color slowly drifting away without a single change in the files.
An individual expense item that almost nobody warns clients about at the start: since 2022 year, Adobe has been charging a separate fee — approximately €15 per month — for access to Pantone libraries inside Illustrator, InDesign and Photoshop. These libraries were previously built-in free of charge, but now designers either pay a subscription or manually enter Pantone numbers from a paper fan and input CMYK values from the Color Bridge reference — this is slower but frees them from dependency on the plugin.
Another practical point concerns the brand book as a document. A properly formatted page with the corporate color should contain not just one value, but at least four: Pantone (standard), CMYK Color Bridge (offset printing), RGB and HEX (digital media), and for brands with industrial coloring — also RAL or NCS. If only HEX is specified in the brand book, any contractor in printing or outdoor advertising will guess the remaining values by eye, and the result will be unpredictable.
In summary: what to remember before the next print run
The difference between Pantone, CMYK, RGB and RAL is not a matter of taste or quality of equipment, but a consequence of the fact that each system has its own physical medium for color: paint, ink, light or a sample on a panel. It is meaningless to argue which system is "more accurate" — one should ask for what production it was designed. If the corporate color is fixed in Pantone from the very beginning, and all other values are derived from it through official tables and ICC profiles, the difference between screen and paper ceases to be an unwelcome surprise and becomes a manageable technical parameter.
