Obsidian Prism

The interface is set upon an absolute dark canvas (#08090f) layered with rounded surface containers (#0f1422) sporting subtle 1px border strokes (#1a2236). Color acts strictly as an intentional focal driver: a signature cyan-to-fuchsia chromatic gradient (linear-gradient(90deg, #2b7fff, #d946ef)) highlights primary actions, key display typography, and metric progress bars, while neutral cool gray (#8f9cae) handles secondary reading. Typography relies on a modern geometric grotesque, using heavy font weights (700-800) at 32px display sizes down to crisp 11px uppercase section trackers with wide 1.2px letter spacing. Component cards leverage generous 20px corner radii, enclosing tightly spaced internal modules (12px radius) for high visual coherence. What captures attention first is the high-contrast synergy between the chromatic rim-lit studio portrait cut against the pitch-black header, effortlessly leading into the glowing primary CTA.

The prompt

Design a dark-mode mobile app interface screen: midnight obsidian surfaces illuminated by razor-sharp cyan and magenta chromatic gradients.

LAYOUT
The mobile page flows sequentially: sticky status/header bar followed by an asymmetrical hero pairing text and an overlapping rim-lit cut-out portrait. Below the hero CTA, modular stacked container cards (20px radius) house distinct domains: 'About Me' (two-column split of bio vs. progress bars), followed by 'What I Do' (horizontally scrollable or gridded service tiles), and ending with 'Selected Work' project cards.

PALETTE (use these exact hex values)
- #08090f — Canvas Obsidian: deep background canvas behind all mobile viewports and root sections
- #0f1422 — Card Surface Base: primary container background for sections like About Me and What I Do
- #161d30 — Sub-surface Elevation: nested tiles, interactive items, and service card fill
- #1c2438 — Surface Border: subtle card outlines, progress bar background tracks, and icon containers
- linear-gradient(90deg, #2b7fff 0%, #d946ef 100%) — Prism Gradient: primary CTA button, headline accent word, logo monogram, and progress fills
- #2b7fff — Prism Cyan: section bullet indicators, inline metadata, and secondary links
- #d946ef — Prism Fuchsia: secondary icon outlines, category labels, and terminal gradient stops
- #ffffff — Text Primary: main headings, button labels, and percentage indicators
- #8f9cae — Text Muted: body copy, subtitles, descriptive card paragraphs, and skill labels

TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, SF Pro Display, Montserrat), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 15px subheading, 18px heading, 32px display. Tracking -0.03em at display, 0.08em at uppercase captions. Plus Jakarta Sans delivers an ultra-modern, technical, yet polished product-designer persona. Its wide geometric apertures provide crystalline readability on OLED dark modes. Inter or SF Pro Display can substitute without losing the geometric discipline.

GEOMETRY & SPACING
Corner radii — cards 20px, links 6px, inputs 12px, buttons 14px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.

DEPTH
Depth is achieved through a 3-tier brightness stepping system rather than drop shadows: base viewport at #08090f, section modules at #0f1422, and nested interactive elements at #161d30. Each elevated surface is delineated by a crisp 1px perimeter border (#1c2438) to simulate dark-mode glass refraction.

IMAGERY
Studio photographic portraiture rendered with high-contrast, dual-color rim lighting (cyan key, magenta fill) against an absolute dark background. Portfolio thumbnails display clean, framed mobile UI screens with rounded internal corners and deep dark-mode UI palettes.

SIGNATURE DETAIL — the thing that makes this design itself
The design's unmistakable hallmark is the cyan-to-fuchsia chromatic gradient paired directly with dual-color rim-lit studio photography. Misusing it involves scattering the gradient across non-essential elements like body copy or large surface backgrounds, which instantly destroys the focused, premium cybernetic aesthetic.

MUST
- Use the cyan-to-fuchsia linear gradient strictly for primary emphasis, interactive highlights, and progress bars.
- Maintain high contrast by keeping secondary text strictly above #8f9cae on dark surfaces.
- Enclose distinct thematic content in #0f1422 cards with uniform 20px radii and 1px #1c2438 borders.
- Prefix section titles with a 6px solid cyan dot and uppercase tracking.

AVOID
- Do not use generic drop shadows; rely entirely on surface lightness tiers and borders for depth.
- Do not apply the gradient fill to more than one word in a single headline.
- Do not use saturated backgrounds across full containers—reserve pure neon for accents only.
- Never drop card border thickness below 1px or exceed 1px; avoid heavy stroke weights.

OUTPUT
Render as a clean, pixel-crisp UI design at roughly 1280:3840. Flat vector rendering, real legible text, no browser chrome, no device mockup frame, no watermark, no lorem ipsum placeholder blocks.

Abyssal Depth

The screen is grounded in an ultra-dark navy canvas (#040a14) that blends directly into deep-sea hero imagery without harsh cutoffs. Vibrant cyan (#4de1fc) and saturated royal blue (#1b4bf5) provide directional illumination, serving both as high-intent callouts and luminous gradients across interactive elements. Typography is clean and geometric, relying on high-contrast white (#ffffff) for display statements and muted slate (#8fa2be) for logistical information. Spacing uses an 8px grid with generous vertical cadence, accented by cards and pills with generous corner radii (ranging from 16px to 24px). The immediate visual hook is the cinematic submarine emerging from caustic ocean beams, anchored by a vibrant gradient CTA button with a seamless directional arrow.

Abyssal Sentinel

The layout splits between a turbulent, full-bleed oceanic photo canvas at the top and an overlapping high-radius clinical white card sheet (#FFFFFF) rising from the lower viewport. Color establishes an immediate cognitive pivot: the brooding marine navy (#10232B) evokes volatile real-world chaos, while soft glacial mint (#BDE4E0) and deep abyssal teal (#0E2A32) communicate calculated technological control. Typography relies on a geometric neo-grotesk with strict hierarchical tracking: loose +1.5px tracking on 11px uppercase category tags, contrasting against tightly-tracked 30px display headings. Layout rhythms alternate between fluid circular pill shapes (radius 999px) and architectural rounded hexagons for photo masking. The eye is first arrested by the stark white display type across the ocean storm, immediately pulled downward by the glowing mint CTA pill into the clean corporate interface below.

Adaptive Motion

The interface is grounded on a warm off-white canvas (#F8F9FB) that allows crisp white rounded containers (#FFFFFF) to float with near-weightless elevation. Primary interaction hinges on a spirited coral red (#F05D5E), which drives the hero CTA, notification ping, ring chart, and selective typographic emphasis on 'moves.'. Typography relies on a modern geometric sans-serif, using weight modulation (Regular 400 to Extrabold 800) rather than scale alone to establish hierarchy. Layout modules are organized into distinct cards with generous 24px corner radii, giving the entire viewport an approachable, pebble-soft hand-feel. A user immediately notices the tactile juxtaposition between the rendered metallic fitness equipment angled against a pastel blush circle (#FAD5D5) and the bright coral progress arc at 72% below.

Aero Coastal

The canvas is structured around an ultra-clean white backdrop (#FFFFFF) framed by an expansive 36px-radius hero image tile depicting a sunlit alpine coast. Color is strictly bifurcated: visual drama belongs to natural photography and subtle pastel surface cards (#FFF1EE, #EDF5FF, #F3F0FF, #EEF9F6), while operational cues use vivid coral (#EE6C58) and sky blue (#3B82F6). Typography is anchored in crisp modern grotesque letterforms, employing stacked 38px display titles over landscape photos and 14px bold headers inside micro-cards. Component shapes maintain generous curvature, from 999px pills to 24px rounded service modules. A viewer immediately registers the high-contrast white typographic stack against the lake landscape before flowing downward into pastel feature tiles.
