Depicting a serene aquatic environment focused on the gentle, flowing grass-like plants growing underwater in shades of ultramarines, giving a deep, almost mysterious atmosphere to the scene. The aquatic grass takes on autumnal hues of faded greens and golden-brown, as if touched by the change of seasons. Some blades may have tinges of yellowish-brown, creating a warm contrast against the cooler water. Sunlight still penetrates the water, but it is softener, casting warm amber highlights on the grass, adding depth and texture. The interplay of light and shadow would emphasise the organic flow of the grass, while the darker hues give the image a sense of quiet, almost melancholic beauty, evoking the feeling of late autumn within a freshwater habitat.
