Design a dark-mode mobile app interface screen: laser-focused dark performance dashboard punctuated with sharp neon lime acceleration.
LAYOUT
The layout is a single-column vertical stack with consistent 16px horizontal margins. The rhythm cascades from a light header bar down to a heavy visual hero card, followed by an immediate horizontal tool rack, a data-dense KPI dashboard, and finally programmatic recommendation lists.
PALETTE (use these exact hex values)
- #0A0C10 — Canvas Dark: Primary screen background behind modular cards and status bar
- #141921 — Card Surface: Container cards housing metrics, banners, and interactive modules
- #B4E63B — Electric Lime: Hero call-to-action pills, active pagination dots, and key statistical highlights
- #98C92C — Deep Lime Accent: Secondary accenting, geometric backdrop splices, and icon accents
- #FFFFFF — White Pure: Primary headlines, numeric metrics, and hero header titles
- #848E9C — Muted Slate Gray: Subtext, section categories, inactive navigation labels, and metric units
- #212833 — Card Border Track: Card dividers, inactive circular track rings, and carousel markers
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Outfit, Inter, SF Pro Display), weights 400/500/600/700/800. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 24px heading, 40px display. Tracking -0.03em at display, 0.02em at uppercase labels. The typographic tone is aggressive, disciplined, and clinical. An athletic, modern geometric sans like Plus Jakarta Sans or Outfit brings high impact in bold weights while remaining exceptionally legible for digital readouts at small scales.
GEOMETRY & SPACING
Corner radii — cards 18px, links 4px, inputs 12px, buttons 999px. Spacing on a 4px unit, 12px gaps, 16px between sections, 390px container, comfortable density.
DEPTH
Depth is created purely through surface color stepping rather than drop shadows. The bottom layer sits at deep #0A0C10, while elevated cards rest at #141921. Selected elements and floating modals utilize a 1px inner stroke (#212833) to delineate overlapping planes against pure black.
IMAGERY
Photography is strictly desaturated or black-and-white fitness imagery showing defined musculature and intense focus. Cutouts overlap dynamic neon lime geometric vectors, creating a sharp 3D pop-out aesthetic. Casual lifestyle or full-color warm photography is strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The juxtaposition of a desaturated grayscale athlete cut out against sharp angular electric lime (#B4E63B) geometry inside a dark slate container. Misusing it means adding full-color photo backgrounds or soft rounded gradient blobs, which kills the raw athletic grit.
MUST
- Use solid #B4E63B exclusively for primary actions, active states, and dominant KPIs.
- Maintain consistent 18px corner radii across all top-level card containers.
- Set card backgrounds strictly to dark slate (#141921) over the deep navy canvas (#0A0C10).
- Keep subheads and inactive labels in cool gray (#848E9C) to enforce strict visual hierarchy.
AVOID
- Do not introduce multi-colored gradient fills; stick to solid electric lime against dark slate.
- Never use soft, high-spread drop shadows; rely on surface contrast and 1px borders.
- Do not set body copy or secondary text to pure white.
- Never use square or sharp corners on interactive buttons; they must be fully rounded pills.
