The majestic St. Basil's Cathedral stands in the middle of Moscow's colorful skyline. Its intricate façade is composed of multiple domes, spires and vibrant patterns of red and blue. Surrounding the impressive structure is a bustling square with a beautiful fountain in the center. Visitors can be seen wandering along its edges, admiring its beauty and taking in the peaceful atmosphere. To best capture this glorious architecture, I would suggest using a range of bold, vibrant colors to bring out each of the intricate details and patterns. Blues, reds, and yellows would be perfect for the exterior, and warmer tones for the inner sections. For the people and fountain, softer, pastel colors would be best to bring out the stillness and serenity of the scene.
