Abstract

A psychophysical experiment was carried out to specify the preferred and natural memory colours corresponding to 24 familiar objects on mobile displays. These objects were selected to cover a large colour gamut in CIELAB space. One hundred and six observers from five different ethnic groups participated. Forty-nine colours for each object were rendered three-dimensionally to cover a large colour range. The results showed inter-observer variations are small between different ethnic groups, about 1.4 and 1.3 CIEDE2000 colour difference units for naturalness and preference, respectively. Comparing the preference and the naturalness colour centres, the preferred colours are brighter and more colourful than naturalness colours, by 1 and 2 units in L* and C*_ab attributes, respectively. Both sets of data show a great hue consistency. The results showed that different ethnic groups agreed well on the objects studied. It was found that the best-agreed objects are strawberry, green apple, tomato, corn and purple grape, and the worst-agreed objects are blueberry, broccoli, smurf, green pepper and blue sky.

不同种族偏好和自然记忆颜色的研究

进行了一项心理物理学实验，以指定与移动显示器上的24个熟悉对象相对应的首选和自然记忆颜色。这些物体被选择为覆盖CIELAB空间中的大色域。来自五个不同民族的106名观察员参加了会议。每个物体的49种颜色被三维渲染，以覆盖较大的颜色范围。结果表明，不同种族之间的观察者间差异较小，自然度和偏好分别约为1.4和1.3 CIEDE2000色差单位。比较偏好和自然度颜色中心，偏好的颜色比自然度颜色更亮、更鲜艳，分别以L*和C*ab属性为1和2个单位。两组数据都显示出很好的色调一致性。研究结果表明，不同民族在研究对象上意见一致。研究发现，最佳约定对象是草莓、青苹果、番茄、玉米和紫葡萄，最差约定对象是蓝莓、西兰花、蓝精灵、青椒和蓝天。
