Design a dark-mode mobile app interface screen: clinical dermatological precision glowing through deep midnight surfaces and electric bio-diagnostic accents.
LAYOUT
The mobile viewport follows a disciplined vertical hierarchy structured around 24px section intervals. The top app bar features the user avatar, greeting, and notification bell, immediately followed by an expansive hero carousel containing AI analysis prompts. Below, the page scrolls through modular chunks: upcoming appointments, a horizontally scrolling treatment track row, and stacked recent activity rows, terminating cleanly above a fixed navigation dock.
PALETTE (use these exact hex values)
- #080C14 — Midnight Obsidian: main application background canvas behind all scrollable modules and status areas
- #101726 — Deep Slate Navy: fill color for elevated interactive cards, horizontal list tiles, and activity rows
- #1E293B — Card Outline Stroke: delicate 1px outer stroke defining container boundaries against the dark background
- #38BDF8 — Electric Cyan: primary interactive accent, hero call-to-action fill, active tab glow, and AI line
- #F43F5E — Clinical Rose: calendar month headers, notification pips, doctor portrait rings, and secondary progress
- #FFFFFF — Pure White: primary headings, appointment names, and prominent numerical values
- #94A3B8 — Cool Slate Muted: body copy, secondary titles, inactive tab icons, and subtext labels
- #1E293B — Deep Indigo Track: unfilled background state for linear treatment progress meters and inactive carousel dots
TYPOGRAPHY
Typeface SF Pro Text (or Inter, Plus Jakarta Sans, DM Sans), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px heading, 22px display. Tracking -0.01em at display, 0.02em at caption. The typographic tone is authoritative, sterile, and premium, evocative of modern medical technology suites. The neutral geometric sans-serif (matching SF Pro Text or Inter) prioritizes legibility at tiny sizes for clinical metrics while commanding attention in high-contrast display titles. For web or Android implementations, Inter or Plus Jakarta Sans serve as exact structural replacements.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 14px, buttons 999px. Spacing on a 4px unit, 12px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created entirely through optical luminance rather than diffuse drop shadows. A three-tier layer system (void canvas at level 0, slate cards at level 1, and the bottom navigation bar at level 2) relies on subtle 1px #1E293B border outlines. Focused elements like the center navigation plus button emit a gentle cyan Gaussian back-glow to simulate illuminated instrumentation.
IMAGERY
Imagery combines high-end clinical aesthetic photography with futuristic bio-diagnostic overlays. Human models are lit under cool studio chiaroscuro with neutral expressions, seamlessly blended into dark cards. Neon cyan diagnostic frequency waves sweep across the skin, signifying algorithmic analysis; casual or overly bright lifestyle photos are strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-tone neon diagnostic wave—a luminous cyan undulating sine line crossing clinical portraiture within a dark midnight card—serves as the definitive signature. It bridges medical dermatology with futuristic AI analysis. Misusing it across everyday informational rows or replacing it with flat vector illustrations would destroy the high-tech clinical identity.
MUST
- Maintain high contrast by keeping card fills at #101726 against the #080C14 background.
- Enclose all card modules within a delicate 1px border stroke using #1E293B.
- Use electric cyan (#38BDF8) exclusively for AI diagnostics, interactive links, and primary CTA buttons.
- Reserve clinical rose (#F43F5E) for date headers, alerts, and distinct treatment progress indicators.
AVOID
- Do not introduce bright, warm yellow or green hues that break clinical diagnostic sophistication.
- Do not use sharp 0px or 4px square corners on content cards.
- Do not apply heavy drop shadows; depth is established strictly through card borders and subtle neon glows.
- Do not allow cyan and rose to clash within the same singular metric bar.
