Design a light-mode web interface screen: sunlit studio warmth paired with precise saas discipline and high-energy cobalt callouts.
LAYOUT
The screen uses an asymmetrical two-column framework anchored by a fixed 240px left-hand navigation sidebar and a flexible content canvas. The main workspace flows logically from an expansive welcome hero down into a 3-tile class queue, followed by an aggregated 4-stat KPI belt. Below the metrics, two balanced 50/50 rows divide analytical views: an Attendance Spline Chart alongside Top Programs, culminating in a Recent Bookings ledger balanced against a warm referral promo banner and full-width newsletter footer.
PALETTE (use these exact hex values)
- #FAF7F2 — Sand Canvas: ambient background for the main viewport and navigation sidebar
- #F4EFEB — Oatmeal Tint: hero promotional banner, stat card blocks, and referral card background
- #FFFFFF — Pure White: high-contrast container background for tables, charts, and input fields
- #2B66E2 — Cobalt Blue: primary call-to-action buttons, active navigation indicator, and data trendlines
- #191B1F — Deep Licorice: primary headlines, prominent metrics, class titles, and table text
- #6F727A — Muted Truffle: secondary metadata, timestamps, table column headers, and subtext
- #22C55E — Meadow Green: positive delta indicators, confirmed status pill backgrounds, and spot counts
- #E08A3C — Ochre Amber: waitlist warning pills and pending attendance indicators
- #EAE5DE — Border Sand: subtle structural card outlines, table row dividers, and input borders
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Outfit), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 20px heading, 26px heading-lg, 44px display. Tracking -0.03em at display, -0.01em at body, 0.05em at caps. The typographic tone is composed, grounded, and modern-boutique. By relying on a clean geometric sans with wide proportions (resembling Plus Jakarta Sans or DM Sans), the UI maintains high data readability while the editorial display scale brings warmth and authority. It avoids sterile corporate numbness through subtle lowercase title play and generous tracking on small-caps metadata.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 8px, buttons 8px. Spacing on a 4px unit, 20px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created almost entirely via tone-on-tone surface transitions (warm sand background behind crisp white panels) rather than vertical drop shadows. When a shadow is present, it is an imperceptible, diffuse ambient bloom (0 2px 8px rgba(35, 30, 20, 0.03)) meant to prevent pure white cards from vibrating against the warm canvas. Interactive items do not lift heavily on hover; they shift surface fill or tint.
IMAGERY
Photography focuses exclusively on athletic, mindful human movement captured in warm, natural window lighting. Subjects are carefully isolated from their backgrounds as transparent cut-outs, allowing natural postures (arches, seated meditation, balances) to interact directly with card boundaries. Harsh studio flash, stock technology setups, or artificial neon gym photography would destroy the serene, holistic tone.
SIGNATURE DETAIL — the thing that makes this design itself
The harmonious clash of a calming, sun-bleached beige interior palette (#FAF7F2, #F4EFEB) with an electric cobalt blue (#2B66E2) interactive anchor, punctuated by transparent human yoga cut-outs breaking the digital grid. If you swap the warm sand for clinical gray or drop the cut-out human forms, it immediately degrades into an ordinary generic B2B template.
MUST
- Reserve vibrant cobalt blue (#2B66E2) strictly for key actions, interactive states, and current data series.
- Use warm oatmeal (#F4EFEB) and sand (#FAF7F2) to soften the analytical rigidity of traditional dashboards.
- Utilize transparent cut-out photography of yoga practitioners overlapping or floating on neutral surfaces.
- Keep all card corner radii strictly unified at 16px, using 8px for inner buttons and input fields.
AVOID
- Do not introduce heavy black drop shadows or sharp multi-layered neumorphic skeuomorphism.
- Never use pure cold grays (#F3F4F6); keep all neutral surfaces leaning warm sand and oatmeal.
- Do not saturate secondary elements with bright accent colors; keep the canvas predominantly calm.
- Never use boxed imagery with harsh square borders when representing featured instructors or hero poses.
