Design Direction Notes — Bold / Retro vs. Direction A (Cream/Heritage)
Color Palette
Red #D42B15 — Primary action color. Matched to logo's red block. More saturated than Direction A.
Yellow #E8C430 — Accent and highlight. Used as a full background on the reviews section. Bolder deployment than Direction A.
Cobalt #1A3A8A — Logo blue. Used for CTA strip. Absent from Direction A.
Near-black #111 — Base dark. Warmer than pure black, harder than Direction A's tobacco.
White #fff — Dominant surface. Clean, high-contrast. No cream.
Typography
Oswald — Display/heading font. Condensed, bold, strong vertical rhythm. WPA-era industrial feel. Replaces Playfair Display from Direction A.
Barlow / Barlow Condensed — Body and italic emphasis. Pairs with Oswald well — same humanist but more open at body size.
Monospace (system) — Labels, tags, metadata. Same role as Direction A — signals precision and craft.
Key Design Differences vs. Direction A
Hero uses actual colored diagonal blocks (not transparent overlays) — the logo geometry is structural, not decorative.
Yellow used as a full section background (reviews) — bold, unexpected, high energy.
Hard borders and grid lines instead of radius/shadow-based separation. Poster aesthetic, not card aesthetic.
Cobalt CTA strip uses the logo's third color — something Direction A avoided. Stronger brand-mark connection.
Gen Z / Millennial Signal Check
Works for younger audiences — Oswald + bold geometry reads as confident craft brand, not outdated corporate. Think Carhartt, Red Wing, Filson ads.
Retro without being nostalgic — The WPA aesthetic is currently experiencing a strong cultural moment. It reads as authentic, not ironic.
Risk: Yellow-heavy sections require strong photography when real images replace placeholders. Warm skin tones and warm metal surfaces photograph well against yellow.
