音色係指音嘅特色。所以，唔同特色嘅音，即使係同一個音高、同一級響度嘅情況底下，人亦都分得出。相同嘅音高、響度，配以相異嘅音色，就好似相同嘅色相、明度配以相異嘅色度咁樣。
Timbre refers to the characteristics of a sound. Therefore, people can distinguish different characteristic sounds, even if they are at the same pitch and at the same level. The same pitch is matched here, with different timbres, just as the same hue and brightness are matched with different colors.
