Color analysis

Objective of the analysis

Color analysis aims to objectively quantify the visual properties of a sample by measuring its colorimetric parameters in standard spaces such as CIELab, RGB, or XYZ . This characterization is essential to ensure the visual consistency of a finished product, meet technical specifications, or identify qualitative deviations related to production, storage, or formulation.

In particular, it allows:

• Measure the shade (L*, a*, b*) of a product
• Quantify colorimetric variations (ΔE) compared to a reference sample
• Validate visual compliance with specifications
• Monitor color changes over time or after treatment

Methods used

• Colorimetry on a portable colorimeter or in a standardized cabin
• UV-Vis spectrophotometry with reflectance or transmission measurement
• Analysis under standardized light conditions (D65, A, TL84, etc.), with white or black background

Affected matrices

• Cosmetics: foundations, lipsticks, masks, powders
• Foods: fruit juices, purees, extracts, functional powders
• Materials: plastics, papers, polymers, textiles, inks
• Industrial or environmental products: effluents, sludge, coatings, packaging

Industrial applications

• Quality control and validation of production batches
• Comparison of colored or natural formulations
• Aging studies, stability to light or temperature
• Verification of packaging or product appearance standards
• Analysis of visual alterations or contaminations
