Design a light-mode mobile app interface screen: airy hospitality onboarding with soft pastel category tokens and grounding emerald actions over clean off-white cards.
LAYOUT
The mobile layout follows a top-down progressive disclosure rhythm: warm greeting and profile header, followed by a left-aligned hero pitch with overlapping cafe illustration, then a four-column industry selector card, a horizontal 3-step onboarding workflow, and finally a live telemetry card anchored at the base.
PALETTE (use these exact hex values)
- #F2F7F7 — Canvas Ice Teal: Root background color across the entire mobile screen canvas
- #FFFFFF — Card Surface White: Raised background fill for content cards and modular content sections
- #258368 — Pine Emerald: Primary CTA button, text links, active step badges, and gauge fills
- #192830 — Heading Slate: High-contrast headings, active metric numerals, and prominent text labels
- #768792 — Muted Slate Gray: Body copy, secondary subtitles, unit labels, and step microcopy
- #E1ECED — Track Cyan: Horizontal stepper connectors and inactive gauge circular arcs
- #EAF7F0 — Pastel Mint: Background disc for cafes/bars category and active step icon circle
- #FDF0EE — Pastel Coral: Background disc for salons and spas category badge
- #EDF6FC — Pastel Sky: Background disc for fitness industry icon and connection steps
- #F7EEFA — Pastel Violet: Background disc for retail category badge container
TYPOGRAPHY
Typeface Plus Jakarta Sans (or DM Sans, Inter, Outfit), weights 400/500/600/700/800. Sizes 11px caption, 13px body-sm, 15px body, 17px subheading, 20px heading, 28px display. Tracking -0.02em at display, 0 at body. The typography is welcoming, modern, and reliable. Utilizing Plus Jakarta Sans gives the numbers and headings a geometric clarity suitable for networking hardware, while rounded terminal shapes prevent it from feeling sterile or overly technical. DM Sans serves as an ideal zero-cost open-source fallback.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 12px, buttons 10px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created almost entirely without drop shadows, using soft chromatic contrast between the #F2F7F7 ice-mint canvas and #FFFFFF cards. Occasional ambient diffusion (0 4px 20px rgba(25, 40, 48, 0.03)) may be applied to ground floating cards on non-tinted devices. Internal elements rely on tonal nesting rather than layered z-index shadows.
IMAGERY
The visual language uses gentle, flat vector character illustrations rendered in harmonious pastel greens, warm yellows, and soft teal hues depicting everyday cafe/retail scenes. Illustrations fade into the background with clean vignette gradients rather than hard borders. 3D renders, high-contrast photography, or harsh outlines are strictly forbidden.
SIGNATURE DETAIL — the thing that makes this design itself
The design's signature element is the quad-tinted pastel circle system paired with deep pine emerald anchors. Category glyphs float within softly hued 56px mint, blush, sky, and violet discs, instantly communicating multifaceted utility without visual heaviness. Misusing this by introducing saturated primaries or removing the enclosing circular discs immediately destroys the airy hospitality aesthetic.
MUST
- Use solid white (#FFFFFF) cards against the soft cyan-tinted (#F2F7F7) canvas to maintain depth.
- Pair deep pine emerald (#258368) strictly with critical CTAs and active state badges.
- Enclose icon glyphs inside 56px pastel circular discs matched to category identity.
- Keep card inner padding uniform at 20px and outer margin consistent at 16px.
AVOID
- Never use generic charcoal or stark black buttons; primary actions must remain pine emerald.
- Do not omit the pastel tinted circular backgrounds beneath sector and step icons.
- Avoid sharp 90-degree corners; card radii must strictly adhere to 20px.
- Do not drop heavy drop shadows; depth is established via tonal canvas contrast.
