Design a light-mode mobile app interface screen: mist-laden coniferous greens layered over pale alpine fog with tactile organic cards and soft circular iconography.
LAYOUT
The mobile viewport follows a strict linear stacking hierarchy starting with an airy photographic crown framing the title 'Forest'. Below the display typography rests a high-contrast dark green feature card spanning full readable width with embedded vertical thumbnail previews. The lower half shifts back to pale ground with a horizontal 4-column categorical icon grid, followed by an expansive secondary spotlight card with soft pictorial backdrop.
PALETTE (use these exact hex values)
- #F3F6F4 — Mist Base: ambient background fill across page scroll and card backdrops
- #223B35 — Deep Spruce: hero card background providing heavy contrast against pale content
- #142823 — Arbor Black: high-priority titles, primary headings, and bold labels
- #617671 — Pine Needle Muted: secondary body paragraphs, captions, and descriptive snippets
- #D4E6DE — Sage Leaf Badge: circular background containers for category icon vectors
- #4FA58C — Canopy Teal Accent: letterspaced overlines and active navigation touchpoints
- #FFFFFF — Alpine Pure White: floating navigation roundels, active tags, and highlight strokes
- #152622 — Shadow Evergreen: compact circle icon buttons inside the dark hero card
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Satoshi), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 22px heading, 28px heading-lg, 42px display. Tracking -0.03em at display, +0.08em at overlines. The typographic tone is composed, academic, and calm, utilizing a modernist geometric sans-serif that balances structural clarity with gentle humanist warmth. It evokes environmental field guides translated into luxury digital editorial formats. Plus Jakarta Sans or Satoshi provide the ideal blend of wide display counters and ultra-clean small-scale numerals.
GEOMETRY & SPACING
Corner radii — cards 24px, links 4px, inputs 16px, buttons 999px. Spacing on a 4px unit, 16px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is created primarily through natural atmospheric perspective (mist fading into white canvas) rather than physical drop shadows. Floating navigation buttons utilize minimal ambient diffusion (0 6px 16px rgba(18, 40, 34, 0.08)) to hover cleanly above the scenery. Dark cards rely on solid tonal contrast against light surroundings to indicate separate functional strata.
IMAGERY
Imagery strictly features authentic alpine, coniferous forest, and misty mountain photography with cool desaturated greens and soft cloud gradients. Visual elements include high-key fog, silhouetted pines, and delicate wildlife motifs like soaring raptors. Saturated tropical greenery or harsh urban textures are completely forbidden.
SIGNATURE DETAIL — the thing that makes this design itself
The distinctive motif is the seamless fusion of foggy alpine landscape photography directly into an off-white mist canvas, interrupted cleanly by deep spruce rounded feature cards (#223B35) hosting rounded vertical photo pills. Losing this transition breaks the tranquil, atmospheric immersion. It is misused when photography is cropped into harsh rectangles rather than breathing softly across the canvas boundary.
MUST
- Use deep organic greens (#223B35) for focal cards to ground the airy mist background.
- Round content cards generously to exactly 24px for a soft organic pebble feel.
- Always set categorical overlines in bold uppercase with expanded tracking (0.08em).
- Keep background imagery desaturated with heavy fog to preserve high contrast for text.
AVOID
- Never introduce harsh artificial neon greens; limit saturation to boreal and sage palettes.
- Do not use sharp 0px or 4px square corners on image thumbnails or cards.
- Avoid solid dark drop shadows; use soft mist-tinted ambient blurs under white roundels.
- Do not center-align body copy; maintain flush left alignment across all text groups.
