The harmonica on the left clearly indicates our instrument.
The button on the harmonica is a distinguishing feature of the chromatic harmonica we played (vs. diatonic harmonica).
Each of the five holes on the harmonica represents each of our five members (although our harmonicas actually have 12 or 16 holes).
The skeleton of the logo is a letter "K" which is the initial of our name and also that of our alma mater - The King's College.
Five "K"s, tightly knitted together, symbolize the close relationships among our five members.
Five levels of shades symbolize the relative pitch ranges of our five instruments.
Finally, the colour of the logo is brick red, which is the colour of the building of our alma mater.
The logo is designed by Ho Pak-cheong, and touched up by Rickel Kwok.
