3D sphere gradient shadow study

A single smooth 3D sphere sits slightly off-center on a matte neutral plane, presented at 16:9 with a horizontal crop that keeps the sphere in the left third and negative space to the right for balance and typographic accommodation if needed. The intent is a calm, studied product-like portrait to showcase form and color transitions for design review. Surfaces are clean and unlettered so that only subtle micro-reflections and abstract lines imply a material finish, with a soft satin skin on the sphere and a fine-grain tabletop texture. A shallow to moderate depth of field resolves the sphere edge crisply while the plane recedes into a gentle, diffuse blur to emphasize isolation. Light sculpts a soft gradation across the hemisphere, producing a warm coral to amber top transition and a cool teal rim hue that echoes the palette tones #FF6B6B, #FFD166, #4ECDC4, and #1A535C. The lighting effect is soft and enveloping with gentle separation and a faint halo where colors blend, creating a calm, neutral atmosphere. Framing is tight to medium with an eye-level viewpoint and normal perceived width, leaving clean negative space on the right for composition breathing and potential overlay. Include one simple prop, a flat matte disc offset behind the sphere to cast an elongated shadow and reinforce the directional gravity of the light. Render in a photoreal 3D finish with subtle material realism and no motion blur so form and color transitions remain the focal study.
