配色之移調研究

Abstract

音樂與色彩之間的關聯性自古以來一直是學者們充滿興趣的研究題目。在大多數的研究都著重於探討音樂與色彩該如何對應之下，本研究從音樂所具有的現象－移調－來探討色彩的配色是否也具有相似的現象。本研究依據音樂在大調或小調之間移調後，音程維持不變的特性，以HSB色彩模型為基礎下，使用隨機色塊組成的參考色盤為刺激，再依受試者填色後所組成的目標色盤進行比對，探討是否具有色相等距平移的效果。從研究結果顯示，當參考色盤與目標色盤之起始色差異不大時，平移的現象較為明顯。此外，在實驗中也發現，誤差高的填色其色相有集中於光譜上的紅黃色區域之趨勢，誤差低的填色其色相則散佈於紅黃色區域以外的光譜上。

For a long time, many researchers are interested in finding the relationship between color and music. A great deal of effort was focused on the mapping between the ordering structures of color and musical tuning systems. A different approach is taken in this study, namely, we concentrate on the color analogue of transposition in music. Are there any transposition rules to entail ‘chord identity’ when we shift the hues of a set of color patches? The HSB color model was used in this study as the basis of hue shift. Five sets of color patches were created as the starting sets of colors. For each set, the color of one of the patches was mapped to another color in an otherwise blank set of patches. The participant was asked to finish the color mapping for all other patches. The inter-patch hue differences were calculated for both the starting sets and the destination sets. It is assumed that the better the agreement in the inter-patch hue differences between the starting and the destination sets, the closer the mapping is to the ideal transposition. We found that if the mapping is over a small range of hue angles, the results are close to a rigid transposition. Larger disparities were found when the starting mapping colors are within the range of from 0 to 60 degrees (the range of red to yellowish orange). Smaller disparities were found within 120 to 360 degrees.
