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.
