Understanding the Color Pick Color System

Why CPS exists

CPS provides stable, readable references that can move across Color Pick tools and exported files.

HEX values are useful but do not communicate family, tone, or intensity. A CPS code adds a structured identity that can be stored in projects, shared in URLs, attached to semantic tokens, and compared through the research dataset.

The system was generated independently for Color Pick and is versioned so existing codes remain compatible.

How the numeric code works

A numeric CPS code combines a family identifier, tone, and intensity suffix.

In CPS 01300B, 01 identifies the Red family, 300 identifies the Bloom tone, and B identifies the Balanced intensity profile. The compact canonical form is CPS01300B, while readable aliases such as CPS 01300B and CPS-01-300-B are accepted.

Older mnemonic codes remain migration aliases where documented, protecting saved projects, URLs, and exports.

Families, tones, and intensities

The library is organized for predictable browsing and programmatic use.

Thirty-six families cover a full hue cycle plus neutral relationships. Tone levels describe broad lightness regions, while Soft, Balanced, and Vivid profiles control intensity. Not every code should be treated as a physical material sample.

Collections group references for practical exploration without changing the canonical identity.

Nearest-color matching

Color Pick uses CIEDE2000 to rank CPS candidates against a resolved source color.

An exact digital match retains the same value. A nearest result reports the code and ΔE00 distance so the user can decide whether to adopt the reference or keep the original as a custom CPS X color.

Nearest matching is useful for normalization and discovery, but semantic role, contrast, gamut, and production context remain part of the decision.

Custom CPS X references

CPS X preserves a user-defined color when the core library should not replace it.

A custom reference can retain the original HEX and metadata while still participating in local projects, role maps, exports, and comparison workflows. Custom references remain local unless the user exports or shares them.

Use CPS X for critical brand colors, client values, or colors whose nearest core CPS reference is not suitable.

Research and export data

CPS is published through versioned JSON, CSV, and CSS assets.

The specification, methodology, dataset, changelog, and accessibility benchmark explain how the library is structured and evaluated. Stable latest aliases support integrations, while versioned files support reproducibility.

Exports include machine-readable values and planning metadata. Consumers should preserve the version and code rather than copying only a display name.

What CPS is not

CPS does not reproduce or claim equivalence with proprietary commercial color systems.

• It is not a licensed third-party swatch library.
• It does not identify a physical ink recipe.
• It does not guarantee a printer or material result.
• It does not make generic CMYK production-accurate.
• It should not be marketed as a replacement for a required proprietary specification.

Practical CPS workflow

Use CPS as a stable reference layer across digital design and planning.

1. 1

   Choose or enter a source color.

2. 2

   Find the exact or nearest CPS reference.

3. 3

   Review ΔE00, gamut, utility, and semantic role.

4. 4

   Keep the original as CPS X when replacement is not appropriate.

5. 5

   Add the selected code to a palette or role map.

6. 6

   Export the CPS code, value, and dataset version.

7. 7

   Confirm physical output through the printer’s proofing workflow.

Key takeaways

CPS connects Color Pick tools through independent, versioned color identities.

• 1,386 references are organized across 36 families.
• Numeric codes encode family, tone, and intensity.
• CIEDE2000 supports nearest matching.
• CPS X preserves custom values.
• Versioned data supports reproducible exports.
• CPS is not proprietary color data or a physical ink specification.
