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 color spaces such as CIELab, RGB, or XYZ . This characterization is essential to guarantee the visual consistency of a finished product, meet technical specifications, or identify quality deviations related to production, storage, or formulation.

It allows, in particular, to:

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

Methods used

• Colorimetry using a portable colorimeter or in a standardized booth
• UV-Vis spectrophotometry with reflectance or transmission measurement
• Analysis under standardized lighting conditions (D65, A, TL84…), with white or black backgrounds

Affected matrices

• Cosmetics: foundations, lipsticks, masks, powders
• Food products: 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 product packaging or appearance standards
• Analysis of visual alterations or contamination
