Green & Black D Emblem
Create a bold, modern logo centered on the letter D, using a vivid green and deep black color palette. Focus on a clean geometric mark with strong, readable silhouette: consider a stylized D formed by negative space, diagonal cut, or overlapping shapes. Primary green should be bright and saturated (lime/emerald tone) contrasted with a near-true black. Present two main treatments: a flat vector version with crisp edges and solid colors, and a subtle 3D/gloss mockup with soft highlights and a matte-black inset. Composition: centered on a transparent background, 1:1 aspect ratio, high-resolution, sharp outlines, scalable for print and web. Include variations on light and dark backgrounds, a small soft drop shadow for depth, and optional metallic bevel/emboss treatment for premium applications. No other text or symbols.
