A monitor screen emits light — it combines light from red, green, and blue rays. This is RGB, an additive model: the more each channel, the closer to white. Paper under a printing machine, on the contrary, does not emit light but absorbs it — the ink takes part of the spectrum, and the eye sees what remains. This is CMYK, a subtractive model based on cyan, magenta, yellow, and black inks. The range that RGB can reproduce is physically wider than what four CMYK inks can print. Bright neon greens, deep blues, and some orange shades in print are simply impossible to achieve — they exist only on the screen.
RGB — a model for everything that glows: websites, applications, presentations, television screens, and outdoor LED constructions. Each channel value ranges from 0 to 255, for a total of over 16 million possible combinations. In web design, the same color is often recorded in HEX code — a six-digit cipher such as #1A73E8, which is simply another way of writing the same RGB values.
CMYK — a model for offset and digital printing: brochures, packaging, catalogs, and most business cards. Four colors are layered on top of each other in varying proportions, and the final color depends heavily on the paper type, the printing machine settings, and even the humidity in the workshop — therefore, the same CMYK code may appear slightly different on different machines.
Pantone is not a mixing model, but a system of standards. The PMS (Pantone Matching System) catalog contains more than 2 400 numbered colors, each mixed according to a fixed recipe and printed on a sample. When a brand book says 'corporate red — Pantone 186 C', the printer mixes the paint exactly according to this recipe, not by matching CMYK visually. This is how corporate colors of Coca-Cola or T-Bank remain the same on packaging, signage, and advertising boards in different countries and with different contractors.
Mechanical translation 'via conversion button' in a graphic program is the source of half the problems with brand colors. The correct sequence looks like this:
| Media | Model | Comment |
|---|---|---|
| Website, app, presentation | RGB / HEX | Specific HEX code is indicated for CSS and design layouts |
| Business cards, brochures, packaging (offset/digital) | CMYK | Color accuracy depends on paper and printing settings |
| Signage, branded clothing, precise printing | Pantone | Sheet printing, colors are mixed according to recipe, not by CMYK code |
| Outdoor advertising, LED screens | RGB | LED glow cannot be physically translated into CMYK logic |
| Embroidery, metallic and neon accents | Special Pantone (Metallic, Neon) | Such colors are impossible to achieve by mixing CMYK at all |
The only reliable way to avoid misunderstandings is to specify all four color values in the brand book or in a separate logo color passport: the Pantone number (with C or U indication), the CMYK formula, RGB values, and HEX. This will take one page of the document, but it will free you from situations where each new contractor — a printing house, an outdoor advertising studio, a website developer — selects the color anew and gets their own shade. A logo without fixed color codes is, in effect, a colorless logo: the form exists, but the recognizable shade that runs through all communication is missing.
