You can measure color reproducibly, but no instrument can capture exactly how one particular person sees every color in every setting. Colorimetry measures light or an object’s spectral reflectance and converts the result using agreed human color-matching data and defined viewing conditions. It models typical human color matching—not your individual vision.
What a color measurement can—and cannot—tell you
Color depends on both the light and the viewing conditions. A painted wall or fabric reflects light, so its apparent color can change with the illumination. A lamp or display emits light directly and must be measured as an emitting source. A useful measurement therefore starts by identifying what you are measuring and documenting the conditions.
Colorimetry uses standard color-matching functions to express measured light on a common basis. The CIE 1931 standard observer is based on color-matching data for defined conditions and is generally used for viewing fields of roughly 1° to 4° at photopic adaptation. The CIE 1964 standard observer applies to larger fields under its specified conditions. These are agreed models, not measurements of your own eyes; individual vision and perception can differ. See the ISO/CIE 11664-1:2019 standard observer specification.
Choose the instrument for the target
| Instrument | What it measures | Best suited to | Key limitation |
|---|---|---|---|
| Spectroreflectometer or spectrophotometer configured for reflectance | A surface’s spectral reflectance under a specified measurement setup | Paint, fabric, paper, and other reflective samples | The reported color depends on illuminant, observer, geometry, sample, and calculation. |
| Spectroradiometer | Spectral irradiance or radiance from an emitting source | Lamps and displays; displays are commonly measured as radiance | Choose a setup appropriate to the source and measurement conditions. |
| Tristimulus colorimeter | Three broad channels intended to approximate human color response | Fast, economical checks, including some display workflows | Spectral mismatch can limit absolute accuracy across a broad range of colors. |
Compare instruments by target type, spectral response, documented uncertainty, sample aperture, geometry, calibration and traceability, speed, and cost. A three-channel meter can be practical when checking small differences in a known workflow; it is not automatically interchangeable with a spectral instrument for absolute measurements across varied colors. NIST’s practical guide describes the underlying measurement trade-offs: NIST, CIE Colorimetry: Part 2: CIE Standard Observers.

Set the conditions before measuring a surface
For an object, the reading depends on the illumination and the geometry: how the instrument illuminates the sample and collects reflected light. CIE and NIST describe four commonly recommended object-color geometries: 45/0, 0/45, d/0, and 0/d. Different geometries can produce different readings, especially for samples whose gloss or texture affects reflection. CIE’s current listed colorimetry report is CIE 015:2018, Colorimetry, 4th Edition.
- Identify the sample. Confirm it is a reflective surface and use an instrument intended to measure spectral reflectance.
- Specify the observer and illuminant. Select the standard observer and illumination required by the application. D65 and Illuminant A are familiar CIE examples; a print workflow may specify another standard illuminant.
- Record geometry and sample handling. Note the instrument geometry, sample preparation, aperture, and relevant surface or texture constraints.
- Calibrate or verify the instrument. Follow its validated procedure and prescribed reference standard; retain the instrument and calibration details.
- Record the result and its limits. Save the color coordinates, the comparison formula if relevant, and measurement uncertainty or the instrument’s documented limits.
This workflow is a practical outline, not a replacement for an applicable industry standard or the instrument manufacturer’s validated procedure.

Understand the reported color values
- CIE XYZ: Three tristimulus values calculated using standard color-matching functions.
- CIELAB: L* represents lightness; a* and b* represent opposing color directions. Values are calculated relative to a specified white point.
- ΔE: A color-difference value whose formula must be named. CIE 1976 ΔEab is the Euclidean distance between two CIELAB points; CIEDE2000 is a distinct standardized formula. CIE lists the latter in ISO/CIE 11664-6:2022. A universal threshold for a visible or acceptable difference cannot be assumed: it depends on the task, samples, viewing conditions, and evaluation method.
For lamps, chromaticity and correlated color temperature (CCT) can help describe white light. CCT alone does not fully describe how well a source renders colors.
Account for uncertainty, not just the device specification
A manufacturer’s accuracy specification does not guarantee that two instruments or measurement setups will agree on every sample. Uncertainty can reflect calibration traceability, measurement geometry, wavelength performance, noise, sample properties, and environmental or viewing conditions. NIST’s 2000 guide gives a specific example: in the measurement context it describes, bandwidths greater than 10 nm can contribute significant errors, and a 20 nm bandwidth can cause errors of up to two to three CIELAB units for saturated colors. That example is not a universal estimate for every instrument or sample. The guide also explains why spectral performance matters when measuring color: NIST’s colorimetry guide.
