Design a light-mode mobile app interface screen: monochrome editorial photography framed by stark chiaroscuro sectioning and electric periwinkle focal anchors.
LAYOUT
The mobile screen is vertically orchestrated in alternating atmospheric zones: a dark visual hero header, a two-column light content stage, and a dark transition card below. The middle section divides horizontally into an asymmetrical split—left side dedicates 52% width to stacked text rows, while right side dedicates 48% to a tall rounded portrait showcase. Navigation and status items anchor cleanly to the top 44px safe zone with standard native spacing.
PALETTE (use these exact hex values)
- #ffffff — Canvas Pure White: Primary surface for the central services and editorial content section
- #121316 — Nocturne Hero Dark: Deep charcoal backdrop for the top hero banner and bottom feature card
- #3d66f6 — Electric Periwinkle: High-emphasis interactive elements, primary CTAs, active pagination, and floating badges
- #101216 — Charcoal Black Text: High-contrast headings and service titles on light background
- #ffffff — Hero Text Light: Main title and icon glyphs on dark hero surfaces
- #737887 — Muted Slate Gray: Secondary descriptors, subtitles, and chevron navigation indicators
- #9fa3af — Hero Subtitle Gray: Descriptive copy over the dark photographic hero banner
- #565a65 — Inactive Dot Slate: Carousel pagination dots indicating non-active slides
- #f0f1f4 — Hairline Divider Gray: Subtle horizontal rules separating service item rows
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display, Helvetica Neue), weights 400/500/600/700. Sizes 10px caption, 11px body-sm, 13px body, 14px body-lg, 20px subheading, 26px heading, 32px display. Tracking -0.02em at display, 0.04em at eyebrow. The typographic tone is architectural, rational, and restrained. Rendered in a clean neo-grotesque sans-serif (matching Inter or SF Pro Display), it achieves authority through weight contrast rather than ornamental fonts. Tight negative letter-spacing on display headlines prevents visual drift, while loose tracking on uppercase eyebrows adds deliberate editorial polish.
GEOMETRY & SPACING
Corner radii — cards 24px, links 4px, inputs 10px, buttons 12px. Spacing on a 4px unit, 16px gaps, 32px between sections, 390px container, comfortable density.
DEPTH
Elevation is completely flat and photographic rather than shadow-driven. Layering is achieved strictly through sharp contrast boundaries between deep dark charcoal surfaces and stark white fields. Overlays (such as the 'Studio' badge) sit directly on the image surface with zero ambient blur, relying solely on opacity and hue contrast.
IMAGERY
Imagery follows high-fashion and architectural fine-art studio photography in rich black and white with deep shadows and controlled rim lighting. Subjects are solitary, sculptural objects (e.g. minimalist wooden chair) or high-contrast studio portraits with defined silhouettes. Saturated lifestyle photography or casual snapshots would completely compromise the gallery-like aesthetic.
SIGNATURE DETAIL — the thing that makes this design itself
The design's signature element is the side-by-side juxtaposition of a tight, hairline-separated service list beside a tall, 24px-rounded monochromatic portrait card pinned with a bright electric-blue floating badge. This breaks the standard full-width mobile list rhythm into an asymmetric editorial magazine spread. It is commonly misused by making the image card too wide or removing the hairline row separators, which causes the list text to visually collide with the photo.
MUST
- Strictly maintain stark chiaroscuro contrast between black media sections and white content zones.
- Reserve #3d66f6 exclusively for focused primary actions, active indicators, and micro-tags.
- Use high-contrast, black-and-white or desaturated fine-art photography for all imagery.
- Maintain a 24px corner radius consistently on all major media cards.
AVOID
- Never introduce warm colored backgrounds; keep the canvas pure white (#ffffff) or dark charcoal (#121316).
- Do not saturate photographic imagery with bright non-editorial colors.
- Avoid applying heavy drop shadows; depth must rely on flat surface value transitions.
- Do not remove the subtle 1px dividers between service items in the list column.
