Déborah Epicoco, Domicele Jonauskaite and Christine Mohr have recently published an article in iPerception, in collaboration with C. Alejandro Parraga, on the application of the gamma correction method.

This inventive study addresses a key challenge in colour perception studies, using Smarty candies: achieving reliable colour display without specialised equipment like chromameters. By testing alternatives — a perception-based gamma estimation task and the industry-standard gamma — the study offers practical solutions for researchers who lack access to precise calibration tools. The study found that both a perception-based gamma estimation and the industry-standard gamma produced colour measurements close to chromameter results. This suggests that using the industry-standard gamma is a practical alternative when precise calibration is not feasible.

The importance of this research lies in its potential to make colour research more accessible and standardised, particularly in settings where exact calibration cannot be achieved. If researchers can confidently use a standard gamma value or a perception-based estimation without compromising accuracy, it could streamline methodologies, save resources, and improve the comparability of results across studies. This approach could make colour research more accessible, ensuring consistency and comparability in studies that rely on accurate colour representation.
