This coloring page features a gathering of three Cossacks seated around a campfire. They are in the shadows of the woods, and what appears to be a ritual is taking place. The drum beats slowly in the background as the men sing softly and chant mysterious words. The atmosphere is thick with tension; something sinister is certainly brewing in the dark night. There is a feeling of danger and dread that hovers over the page.
When coloring this image, I would suggest boosting the otherworldly atmosphere with cooler tones. The blues, greens, and greys of night would create an air of mystery, while a few warm oranges for the firelight would bring a sense of life and contrast to the background. Something ominous should come through - use strong, inky purples and blacks for accents, with a few bold bursts of red sparingly placed for contrast. The Cossacks should stand out from the dark surroundings, so select lighter colors to bring that sense of humanity to the table. It's a great opportunity to experiment with both light and dark colors, creating an eerie and entrancing composition.
