Purple dahlia bloom rendered against black background

Three-dimensional digital rendering of a dahlia flower with radially arranged petals in purple and magenta gradient tones. Central dark core with geometric symmetry. Multiple petal layers progress outward from center, each segment displaying light-to-dark transitions and dimensional shading. Black background provides high contrast. Petals exhibit precise volumetric modeling with gradated color fields ranging from pale lavender at center to deep purple at outer edges. Digital render demonstrates calibrated lighting and surface texture application across bloom structure.
