This instrument has a beautiful golden colour. The body is slim and curved, and the neck appears long and thin. At the top of the neck is the mouthpiece which houses a thin reed. Blowing into the mouthpiece and pressing the keys will create a range of notes. To colour this image, a cool metallic gold could be used to represent the body of the instrument. The keys could be a brighter golden shade or silver to give them a more metallic feel. The mouthpiece could be kept black to stand out from the metal and hint at the sound produced when in use. To finish off, a deep blue or indigo could be used along the neck and body of the instrument to provide a nice contrast and tie the colour scheme together.
