Glowing heart shape rendered with orange and blue fire effects.

Digital 3D rendering employing volumetric light diffusion and particle systems. Heart silhouette constructed from flowing flame geometry with gradated color transitions from deep indigo through crimson to golden yellow. Left hemisphere illuminated in cool blue tones; right side features warm orange-red spectrum with yellow highlights. Atmospheric smoke dispersal uses density gradients; specular highlights emphasize flame turbulence. Dark background isolates subject through high contrast values. Technical execution demonstrates advanced shader work with realistic refraction indices and light scattering algorithms.
