The coloring page features three men dressed in matching blue uniforms and white masks. Standing proudly in front of a giant white machine, two of the men hold hoses while the third man is controlling the panel. I would recommend coloring the men's uniforms in a dark blue, their masks in a bright white and the hoses in a bold yellow. While the machine can be filled in with an array of shades of white, grey and silver. To further bring out the look, add some bright red to the control panel and a golden yellow to the edges of the machine. Let your imagination run free with the rest of the details in the scene and enjoy!
