A palette composed of multiple colour patches can express lots of information. This study aimed to explore the factors that influenced colour palette preference, including colour attributes and colour differences between colour patches. A new attribute called Delta_Order for calculating the colour difference of a palette was presented, which fully considered the colour difference and the placement. In order to comprehend colour palette preference intuitively, a prediction model of palette preference was proposed based on lightness, chroma and the new metric Delta_Order. Two psychophysical experiments including analyzing and validating experiments were conducted. Fifty observers were invited to evaluate the colour palette preference. The results indicated that lightness played an important role in colour preference, but colour preference was not related to hue angle. For Delta_Order, there was a significant negative correlation between the new metric and preference score since the Pearson correlation coefficient was -0.801. This meant that observers preferred the palettes with low Delta_Orders. According to the validating test, it confirmed that the proposed prediction model had a good stability. The predicted trends were consistent with the true results, and the scores were similar to each other. These analysis results had a certain guiding significance in design and industry about colour.
由多个色块组成的调色板可以表达大量信息。本研究旨在探索影响调色板偏好的因素，包括颜色属性和色块之间的颜色差异。提出了一种名为Delta_Order的新属性来计算调色板的颜色差异，该属性充分考虑了颜色差异和色块布局。为了直观地理解调色板偏好，基于明度、色度和新度量Delta_Order提出了一种调色板偏好预测模型。进行了两个心理物理学实验，包括分析实验和验证实验。邀请了50名观察者评估调色板偏好。结果表明，明度在颜色偏好中起着重要作用，但颜色偏好与色相角无关。对于Delta_Order，由于皮尔逊相关系数为-0.801，新度量与偏好得分之间存在显著负相关。这意味着观察者更喜欢Delta_Order值低的调色板。根据验证测试，证实所提出的预测模型具有良好的稳定性。预测趋势与真实结果一致，得分也彼此相似。这些分析结果在颜色设计和行业方面具有一定的指导意义。
