Design a captivating winter-themed coloring page for a 'Winter Wonderland' coloring book that showcases the beauty of both snowy and rainy days. The page should depict a picturesque landscape that transitions from a snowy scene on one side to a rainy scene on the other. Include elements such as a snow-covered forest with tall pine trees and playful snowmen on the snowy side, and a cozy café with people enjoying warm beverages and colorful umbrellas on the rainy side. Ensure there is plenty of space for coloring, intricate patterns like snowflakes, and raindrops on the windows. The overall design should capture the enchantment of winter's contrasts, from the serene snowy moments to the cozy, rainy days.
