This fantastic Tuba has been beautifully drawn and depicted on the coloring page. The brass bell is round, and the tube is curved gracefully to give the image an elegant, ornamental feel. The coloring page is a wonderful opportunity to bring the Tuba to life! You could choose to color the brass parts with a warm shade such as gold or yellow for a subtle antiquated feel. To emphasise the contrast between the metal elements and the smooth curves, you could choose a richer bronze color. Alternatively, you could use different shades of brown or blue to evoke a classic and timeless design. For some pops of color, paint the mouthpiece in a vibrant red or purple. You could also add some final touches with glitter for a touch of glamor and shine.
