The coloring page depicts an elderly troll called Tsvetan. He has bulging yellow eyes, a blue face and a long, crooked nose. A belt holding up his brown coat is clasped around his neck and his thin hair is tucked neatly in his long brown beard. Tsvetan looks rather glum, as if he had seen many difficult years. To bring life to him, you could use bright colors to make his features stand out. Shades of green, yellow and blue would bring out his face, while adding tinges of orange and pink to the dark blues and browns of his coat would create a cozy contrast. You could also add hints of purple in the shadows of his coat and hair to create an even more magical feel. Let your creativity flow and don't be afraid to experiment! Tsvetan is sure to come alive with bright and vibrant colors.
