Place a series of colored squares and circles on a black background. These shapes are ethereal, semi-transparent, allowing the colors to mix and blend effortlessly. The number of shapes is deliberately kept small, creating an intimate and captivating display. Vary the sizes of the squares and circles to add depth and dimension to the arrangement. Some shapes may appear closer to the viewer, while others recede into the distance, creating an intriguing sense of perspective. The semi-transparent nature of the shapes intensifies their ethereal quality, making them appear almost weightless, floating in the darkness. Experiment with the colors of the squares and circles to create different moods and atmospheres. You can opt for soft pastel hues for a dreamy and soothing effect or go for vibrant and contrasting colors to make a bold statement. Whatever combination you choose, the interplay of light and shadows against the black background will undoubtedly create a visually stunning composition that captivates viewers.
