Use case: stylized-concept. Asset type: polished art-direction comparison board for KidStock, an educational app for ages 8–14. Create one landscape high-resolution image, approximately 3:2, clean white background, two equally sized panels side by side. Primary request: a NEW exceptionally cohesive family of bright, tactile 3D CLAY icons, shown in two color treatments to choose between. This is NOT a webpage mockup. It is a precise side-by-side icon design comparison. Typography: minimal dark navy friendly sans-serif. Top title exactly "KidStock · Clay icon family". Left panel heading exactly "A · Solid clay". Right panel heading exactly "B · Gradient clay". At bottom small sentence "Same shapes. Same light. Two colour treatments." Each panel contains the SAME NINE icons in the SAME 3 by 3 grid, evenly spaced, each with a simple readable dark-navy label below. Order: row 1: Learn (closed chunky book with rounded spine and small bookmark); Quizzes (chunky freestanding question mark on a small rounded tile); Missions (rounded flag on short chunky pole and small base). row 2: Invest (puffy rounded wallet with one simple coin); Concepts (simple chunky light bulb on short rounded base); Discovered (chunky round compass with one arrow). row 3: Watchlist (thick rounded bookmark with a small inset star); Invested (two chunky coin discs with a tiny two-leaf sprout); Mastered (round thick medal with small star and two short rounded ribbon tails). ICON FAMILY RULES: every icon looks sculpted by the SAME artist from the SAME soft matte modeling clay, at the SAME scale, same thickness and rounded bevel radius, same very slight front three-quarter camera angle, same upper-left broad softbox illumination, same gentle contact shadow below. All upright, no random rotations. Strong simple silhouettes, low detail, no thin lines, no outlines, no glossy plastic, no glass, no metallic reflections, no stickers, no extra floating decorations, no sparkles, no faces. Use smooth tactile clay, not rough or grained. Equal optical weight, maximum 2 main colors per icon plus a tiny off-white detail. Images should feel vivid and premium, not babyish or pastel washed-out. COLOUR SYSTEM IN BOTH PANELS: Learn vivid mint #23F8B5 with dark turquoise secondary; Quizzes saturated sunny yellow #FFE447 with a tiny warm orange secondary; Missions vivid violet #8B5CF6 with violet-blue secondary; Invest bright coral #FF6555 with a yellow coin; Concepts mint with tiny yellow accent; Discovered electric sky #5CE7FF with royal-blue compass arrow; Watchlist sky with blue star; Invested coral with yellow coin and tiny mint sprout; Mastered violet with yellow star. A SOLID CLAY: each clay component has one clean saturated uniform pigment. Only physically natural soft lighting/shadows create depth. Absolutely NO painted color gradients, no ombre, no white glossy highlight bands. B GRADIENT CLAY: IDENTICAL geometry to A. Controlled smooth TWO-TONE pigment blends only WITHIN the main clay body, following the same upper-left to lower-right direction. Mint-to-turquoise for Learn; yellow-to-soft-orange for Quizzes; violet-to-blue-violet for Missions; coral-to-warm-pink for Invest; same hue-family logic for other icons. Keep main body vivid and color coding instantly recognizable. Natural matte shading stays identical to A. No rainbow blends, no iridescence, no glow, no gradient background. Keep plentiful white breathing room; subtle pale grey vertical divider. Labels must be exactly spelled. Do not imitate the previous SVG shapes. The point is convincing unified clay material and a fair controlled A/B comparison.
