摘要

博物馆保护指南将敏感艺术品的照度限制在可能导致物体被认为色彩不足的水平,这种现象被称为亨特效应。先前的显色性研究发现,红色的饱和色域会持续增加感知到的饱和度和个人偏好。我们进行了一项研究,以评估美术的视觉体验,该视觉体验是由一个红色饱和色域家族所限定的,由其TM-30色域分数(表示为[公式:见文本])和位置在黑体轨迹(Duv)之上或之下唯一识别。[公式:见文本]和Duv根据响应面方法系统地变化,旨在映射二阶项和相互作用,在3000 K和50 lx下,分别为96≤[公式:见文本]≤124和- 0.0212≤Duv≤0.0036。31位naïve参与者每人在一个模拟艺术画廊中,根据偏好、饱和度和自然度对应的语义尺度,在9个独立呈现的场景下评估一对画作。该研究确定了一个偏好的响应面,映射了[公式:见文]和Duv之间的相互作用,预测Duv = - 0.013在[公式:见文]和Duv = - 0.005在[公式:见文]更受欢迎。增加[公式:见文本]会持续增加个人偏好和感知饱和度。

Fine art under low illuminance: Gamut and tint
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.
