Recommended methods for conducting human factors experiments on the subjective evaluation of colour rendition

This article explores the best practices for conducting psychophysical experiments that investigate how colour rendition influences perception of architectural environments. We offer guidance covers all stages research from preliminary development to publication, focusing especially on qualities such as perceived naturalness, vividness, preference or acceptability in response changes spectral power distribution light sources. is intended be a consolidated guide researchers and reviewers this type research. Key recommendations include: (1) New work should motivated by clearly expressed questions and, when possible, explicit hypotheses build existing body knowledge, (2) visual stimuli comprising distributions targets deliberately engineered probe questions, (3) designed lessen potential biases, (4) reporting experimental conditions statistical analyses thorough (5) Results contextual, resisting overgeneralization cannot supported data. Our motivation encourage high-quality credible discourage poor quality slows scientific progress misuses resources.
