How I Document Color for Brand Consistency Across Teams

The Format Problem

A brand color exists across multiple production environments simultaneously. It's printed on business cards by an offset printer. It appears on a website rendered by a browser. It's applied to merchandise by a screen printer. It's used in a PowerPoint by a marketing coordinator.

Each of these environments uses a different color model. A single hex value doesn't solve the color consistency problem — it only solves the screen/digital portion of it. Comprehensive color documentation provides every format the brand needs, not just the one the designer is most comfortable with.

The Six Formats I Include

For every primary and secondary brand color, I document six format specifications.

Hex is the standard for digital and screen use. Every designer, developer, and non-technical team member knows what a hex value is. It's the starting point.

RGB is the underlying model for screen color. Some tools and environments expect RGB values rather than hex. I include the decimal RGB (0–255 range) and note that hex is the derived format.

CMYK is for print. This is not a direct conversion from hex — CMYK values should be derived from the Pantone anchor color for the most accurate print reproduction. Different paper stocks have different optimal CMYK conversions, so I often provide two: one for coated stock and one for uncoated.

Pantone Coated (C) is the spot color reference for coated paper applications. The C suffix matters — Pantone colors look different on coated vs. uncoated stock, and the coated version is the standard for premium print work.

Pantone Uncoated (U) is the spot color reference for uncoated paper. Ink absorbs differently into uncoated stock, so the visual result can differ significantly from the coated version. For brands that use a lot of uncoated material, I test this specifically.

RAL or NCS is for paint and surface coating applications. Brands that apply their color to physical environments — retail spaces, vehicles, signage structures, furniture — need a color standard that translates to paint systems. RAL is common in Europe; NCS is used in architectural contexts. I research which system is most relevant for the client's primary markets.

How I Derive CMYK From Pantone

The correct approach: Pantone publishes official CMYK conversion values for each Pantone color. I use these as my starting point, then adjust if necessary based on a printed proof on the actual stock.

The incorrect approach: converting the hex or RGB value to CMYK using software's automatic conversion. These conversions use generic color profiles that often produce poor results. A rich, saturated blue can come out muddy and greenish when converted through automatic CMYK translation.

Naming Colors in the Brand System

I name every brand color with a proper name, not just a descriptor. "Primary Blue" is a functional name for internal reference. But color names create personality and memorability.

I derive color names from the brand's world — its geography, history, materials, or values. A construction brand might name its primary orange "Copper" and its navy "Steel Blue." A coastal hospitality brand might name its palette after local landmarks or natural features.

These names show up in guidelines, in asset libraries, in design system documentation. A designer reaching for the right color is more likely to reach for "Harbor" than for "Brand Secondary."

Making the Documentation Usable

Color documentation that's buried on page 23 of a brand guidelines PDF isn't useful to the person who needs it daily. I publish color specifications in multiple formats:

A one-page color reference card with all primary and secondary colors, all format values, and color names. This gets pinned in Slack, saved to the shared drive, and printed and taped to monitors.

A design system library with color swatches pre-loaded in the correct hex values, named correctly, and organized by role. This is the in-tool reference for anyone designing in Figma or equivalent tools.

The comprehensive guidelines PDF for reference when unusual production questions arise.

Three layers of documentation, three levels of accessibility, one source of truth.
