Museum conservation guidelines restrict illuminance for sensitive artwork to levels that can cause objects to be perceived as less colourful, a phenomenon known as the Hunt effect. Previous colour rendering research identified red saturating gamuts that consistently increased perceived saturation and personal preference. A study was conducted to evaluate the visual experience of fine art illuminated by a red saturating gamut family constrained to be uniquely identified by their TM-30 gamut scores (denoted as [Formula: see text]) and position above or below the blackbody locus ( Duv). [Formula: see text] and Duv were systematically varied according to response surface methodology, designed to map second-order terms and interactions, with 96 ⩽ [Formula: see text] ⩽ 124 and −0.0212 ⩽ Duv ⩽ 0.0036, all at 3000 K and 50 lx. Thirty-one naïve participants each evaluated a pair of paintings in a mock art gallery under nine independently presented scenes along semantic scales corresponding to preference, saturation and naturalness. The study identified a response surface for preference that maps an interaction between [Formula: see text] and Duv, predicting Duv = −0.013 was preferred at [Formula: see text] and Duv = −0.005 was preferred at [Formula: see text]. Increasing [Formula: see text] consistently increased both personal preference and perceived saturation.
