Inside an enormous cave made entirely of multicolored crystals, the vast space is bathed in a bright, clear, and almost pure white light, creating a magical and ethereal atmosphere. The crystals, in varying sizes, glow with luminous intensity, reflecting and refracting countless iridescent hues inspired by the delicate tones of an opal--soft blues, pastel pinks, vivid greens, and shimmering purples. The brilliant white light enhances the clarity of the reflections, casting dazzling patterns across the cavern and illuminating every intricate crystalline formation. The walls, ceiling, and floor are adorned with glowing crystals that radiate light and color, filling the immense space with a breathtaking sense of wonder. The photorealistic scene captures every fine detail, from the sharp edges of the crystals to the vibrant interplay of light, creating an otherworldly beauty. --ar 16:9
