The scene shows Mickey Mouse and his three closest pals standing in a neat row, each holding a brightly colored balloon. Mickey is grinning from ear to ear and has a vivid red balloon firmly in his grasp, while Minnie is just as jubilant with a cheery yellow one. Donald's bright blue balloon and Goofy's grassy green one complete the picture, with all four characters smiling and looking directly at the observer. To color this illustration, I suggest beginning with the balloons, as their hues will stand out the most. Start with a solid, intense color for each balloon - red, yellow, blue and green - and take it from there. Add shadows and reflections to make the balloons appear as if they are actually floating in the air, and top them off with thick, bold outlines. The mice can then be filled in with solid but subtle shades that correspond to their respective balloons. Finally, give Mickey, Minnie, Donald and Goofy each a bright, distinctive glow and the image will be complete.
