Create a visually striking and culturally rich coloring page that explores the heritage of ancient Egypt. The main focus of this full-page, medium greyscale coloring canvas is the Egyptian flag, represented in simple line art, wafting gallantly in the foreground. The flag's three equal horizontal bands must be outlined, allowing the colorist to fill in the black, white, and red sections, with the national emblem, the golden Eagle of Saladin, in the center white band. Behind the flag, sketch the timeless wonders of Egypt: the majestic pyramids. Include the Great Pyramid of Giza, along with two slightly smaller neighboring pyramids, maintaining a realistic perspective. These monolithic structures should be drawn with clear lines and geometric precision, using shades of grey to create a sense of depth and shadow, without overwhelming the colorist. To the right of the pyramids, incorporate the enigmatic Sphinx. Depict this mythical creature with its lion's body and human head with medium-level detail, preserving its mysterious expression. Emphasize its iconic headdress and the contours of its weathered stone body through thoughtfully placed greyscale shading. Frame the entire scene within a decorative border inspired by ancient Egyptian hieroglyphics or ornamental patterns to add a finishing touch to the composition. Provide areas of varying complexity within the artwork to accommodate colorists of different skill levels, from novice to expert, ensuring a captivating and enjoyable experience. Allow space for experimentation with color blending, layering, and shading, to encourage creativity and mindfulness in this culturally evocative coloring adventure --ar 17:22 --s 50
