Color combination criteria are said to entail an affective response in interior design. We investigated the color combination criteria that orient the preference of current observers, after Le Corbusier's 1931 Salubra keyboards. We explored the similarity/contrast in Natural Color System (NCS) hue, blackness, and chromaticness in 312 combinations with four colors, two backgrounds and two accent colors, coming from 43 individual colors, on the walls of a simulated interior of a bedroom from the Swiss Pavilion (Le Corbusier, 1930-1931). Participants were 644 students of architecture and interior design in Western Europe and Near East, who evaluated with a Likert scale their preference for virtual images via an online survey. Results indicate that the most preferred color combinations are those with hues closer in the color wheel, being the similarity between hues in the backgrounds more important than in the accent colors, and with NCS B30G to G as the most preferred hues. Observers preferred color compositions with blackness under 10% and similar blackness between the two background colors, together with a certain blackness contrast between these background colors and the two color accents. Similarly, observers liked color compositions with low chromaticness and low chromaticness difference among the four colors of the composition.

就自然色彩系统属性的相似性/对比而言，对室内建筑中强调色和背景色的偏好

据说颜色组合标准需要在室内设计中产生情感反应。在 Le Corbusier 1931 年的 Salubra 键盘之后，我们调查了当前观察者偏好的颜色组合标准。我们在卧室模拟室内的墙壁上探索了自然色彩系统 (NCS) 色调、黑度和色度的相似性/对比，其中包含来自 43 种不同颜色的四种颜色、两种背景和两种强调色的 312 种组合。瑞士馆（勒柯布西耶，1930-1931）。参与者是西欧和近东的 644 名建筑和室内设计学生，他们通过在线调查使用李克特量表评估他们对虚拟图像的偏好。结果表明，最喜欢的颜色组合是色轮中色调更接近的颜色组合，背景中色调之间的相似性比强调色更重要，并且 NCS B30G 到 G 是最喜欢的色调。观察者更喜欢黑度低于 10% 且两种背景颜色之间的黑度相似的颜色组合，以及这些背景颜色和两种颜色强调之间的某种黑度对比。同样，观察者喜欢低色度的色彩组合物，并且组合物的四种颜色之间的色度差异也很小。再加上这些背景颜色和两种颜色之间的某种黑色对比。同样，观察者喜欢低色度的色彩组合物，并且组合物的四种颜色之间的色度差异也很小。再加上这些背景颜色和两种颜色之间的某种黑色对比。同样，观察者喜欢低色度的色彩组合物，并且组合物的四种颜色之间的色度差异也很小。
