This coloring page shows Mickey Mouse and his friends on very thin ice. The ice looks like it is about to crack beneath them, and although they are laughing and enjoying themselves, they don't seem to realize the danger. Their bright colors make them stand out against the wintry white background, so you can easily color them in with a bright palette. I'd suggest starting with yellow or red, as those are Mickey's signature colors, then exploring other warm colors like pink and orange to shade in the details. Add some cool tones to the ice, like blues, purples, and grays to make it stand out. Final touches can include highlights in the ice, sparkling silver glitter to show that the water is freezing, and various shades of gray to depict shadows.
