Portal Through Ancient Stone Coloring Page

Carved stone blocks stack to form an arched gateway, each block showing weathered surface textures with cracks and irregular edges for this coloring page. Beyond the threshold, spiral galaxies swirl in multiple directions while scattered stars of varying sizes dot the cosmic expanse. Runic markings follow the arch's inner curve, their angular shapes providing geometric contrast against both the rough masonry and flowing celestial patterns. The stonework needs gray tones built up with crosshatching to show depth in the cracks and aged surfaces. Try purples, deep blues, and violets for the void, adding lighter blues or whites where the spiral patterns create luminous centers. The runes could use metallic shades like gold or silver to stand out against darker stone, making them appear carved or glowing with ancient power.
