This coloring page features a stunning representation of the international symbol of Women's Day - a lily of the valley. It is drawn in shades of white, green, and pink, and is surrounded by a pink ribbon with "Happy International Women's Day" written in white. To color this page, I would choose a bright and vibrant pink for the ribbon that contrasts against the white lily of the valley. For the lily, I suggest a very pale lilac or pale yellow to represent the white petals and grass green for the leaves. I would then use a lighter version of the pink from the ribbon to shade the edges of the lily of the valley to provide a more realistic look. A silver or light gray marker could also be used to add a touch of sparkle. Finally, a black marker could be used to create an outline for the lily of the valley and the pink words to give the picture a more finished look.
