Benefits

What Color Managed Library makes possible.

01Spectral instead of only LAB or RGB values

Spectral data describes the full reflectance curve of a color, not just three coordinates. It reveals metamerism, keeps the color independent of light source and device, and provides the only data basis that stays reproducible across the supply chain.

02Light simulation D65, A, TL84 …

Every color can be simulated under daylight (D65), incandescent (A), retail floor light (TL84) and further standard illuminants at a click. You catch metamerism risks before the product hits the shop floor.

03Standard, lab and bulk values connected

Standard, lab sample and bulk production live in one record. dE values, tolerances and approvals are linked, instead of scattered across spreadsheets, emails and supplier portals.

04Visible to every stakeholder, worldwide

Designers, suppliers, QA and compliance work worldwide on the same validated color. Roles, permissions and an audit trail are built in, so every change stays traceable.

05Search and cross-reference

Find colors by name, code, season, supplier, collection or spectral proximity. Cross-reference links external standards (Pantone, RAL, in-house codes, supplier IDs) to your spectral reference, so one color stays one truth no matter how many names it carries.

Workflow

How Color Managed Library fits into your reality.

Store the standard

Spectral reference from measurement, not from gut feeling.

Validate the match

MatchBox compares lab and bulk data against the standard.

Distribute

Designers, suppliers and QA work on the same color.

Spectral color science

What makes color truly comparable.

Light source · D65

Spectral reflectance curve, live.

Switch color and light source. See why the same spectrum projects to a different RGB and LAB under different light.

Light source

Illustrative spectra and simplified observer data. In DMIx you work with real measurements from your spectrophotometer.

Spectral vs. RGB / LAB.

Why brands, suppliers and QA work from spectral data, not display projections.

Property	RGB	LAB	Spectral
Data basis	3 channels	3 coordinates	Full reflectance curve
Light source dependency	High	Medium	None (illuminant independent)
Metamerism detectable	No	Partially	Fully
Device independent	No	Partial	Yes
Supply chain reproducibility	Low	Medium	High
Suitability for QA and audit trail	Not suitable	Limited	Recommended
Recommended use	Screens	Design approvals	Production and QA across the supply chain

Data basis

RGB: 3 channels
LAB: 3 coordinates
Spectral: Full reflectance curve

Light source dependency

RGB: High
LAB: Medium
Spectral: None (illuminant independent)

Metamerism detectable

RGB: No
LAB: Partially
Spectral: Fully

Device independent

RGB: No
LAB: Partial
Spectral: Yes

Supply chain reproducibility

Spectral data is the source. RGB and LAB are derived projections, valid only under an assumed light source.

Tool · DMIx Measure

DMIx Measure: color measurement, color metrics and color-accurate display.

Color perception plays a central role in product development and evaluation. That is why a key part of our work is the objective measurement and colorimetric analysis of colors.

DMIx Measure is the tool for this, as part of the Color Library. With DMIx Measure, measurement devices from the major manufacturers can be connected, colors measured and colorimetrically analyzed. Colors are no longer just described or photographed, they are translated into objective digital values.

A particular strength of DMIx is that the platform is fully color managed. Users can store a monitor profile in their setup and, in combination with a calibrated monitor, achieve a color-accurate display. Digital color and material data is not only measured and stored, it is also controlled and reliably visualized.

Why does this matter?

Because digital color values create a shared foundation. Everyone involved can access the same value and talk about the same color.

01Less subjective interpretation
02Better communication
03Clear specifications for suppliers
04Measurable quality control
05Complete colorimetric review and evaluation
06Color-accurate display on calibrated monitors
07Reliable basis for a wide range of use cases

Factors that can influence color perception, such as environment and lighting, are reduced or removed from the assessment.

What becomes possible?

Measured and colorimetrically analyzed colors can be used for different purposes and converted mathematically, for example for:

01Color-accurate on-screen display
02Print processes
03Industrial color processes
04Quality control
05Cross-referencing with existing supplier colors
06Communication between brand, supplier and production

Once a supplier has printed, dyed or otherwise produced a specified color, it can be checked objectively how closely that color was matched.

This matters especially in digital review: DMIx reduces not only the subjectivity of color measurement, but also the uncertainty of color display on screen.
