Design a light-mode web interface screen: a pitch-black curation frame holding brilliant cadmium red, coral, and cobalt moodboard tiles in razor-sharp harmony.
LAYOUT
The viewport is vertically split: a persistent 220px dark navigation rail on the left, flanked by a two-tone scrolling content viewport on the right. The upper light canvas features a top utility bar, followed by a bold left-aligned display headline, filter pills, and a rhythmically varied multi-span mosaic. Beneath this gallery lies a full-width midnight footer section organizing recent project decks and assistant quick-actions.
PALETTE (use these exact hex values)
- #121418 — Sidebar Obsidian: Background for primary persistent vertical navigation and workspace profile panel.
- #F5F6F8 — Gallery Canvas: Light mode workspace background hosting the header, filter controls, and dynamic asset mosaic.
- #0E1116 — Floor Charcoal: Deep contrast section background for lower project decks and studio assistant toolbars.
- #2563EB — Cobalt Primary: Hero action buttons, active tags, and primary electric blue asset cards.
- #E53E2A — Vermilion Accent: Punchy red-orange card backings and high-contrast vector container backgrounds.
- #F38B74 — Peach Coral: Soft saturated coral tone used for typographic cover cards and warm asset containers.
- #E0EEFA — Powder Sky: Subdued pastel blue for linework illustration tiles and delicate preview cards.
- #F8DFD8 — Blush Sand: Warm tinted neutral backdrops for classical figurative references and etching cards.
- #111827 — Ink Core: Primary typography on light surfaces, including display titles and selected tags.
- #6B7280 — Muted Slate: Card category chips, item counts, secondary subtitles, and dormant navigation labels.
TYPOGRAPHY
Typeface Inter Display (or Plus Jakarta Sans, SF Pro Display, Helvetica Now), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 16px body-lg, 20px subheading, 32px heading, 40px display. Tracking -0.03em on display titles, -0.01em on body. Clean, authoritative, and deliberately invisible. By employing a tightly-tracked neutral grotesque (matching Inter or Plus Jakarta Sans), the typography acts as an objective curation apparatus that allows the wild hues and expressive illustrations inside the tiles to command attention. It evokes contemporary Swiss international typography repurposed for high-end digital design tooling.
GEOMETRY & SPACING
Corner radii — cards 14px, links 4px, inputs 8px, buttons 8px. Spacing on a 8px unit, 16px gaps, 64px between sections, 1440px container, comfortable density.
DEPTH
Depth is almost entirely planar and graphic rather than skeuomorphic. Flat coloured planes sit directly atop the #F5F6F8 canvas with 0px box-shadows, separated solely by 16px negative space. Modals and floating action pills use extremely subtle 1px translucent strokes and deep scrims rather than diffuse blur shadows.
IMAGERY
Visual assets combine three distinct idioms: punchy serif wordmarks rendered as flat vector art ('BOLD'), delicate neo-classical etching illustrations rendered in single-hue strokes, and intense theatrical photography bathed in monochromatic red/amber gel lighting. Raw, generic lifestyle stock photography with natural lighting is completely prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The rhythmic contrast between the pitch-dark utility chrome and an asymmetrical mosaic of flat, solid-tinted card tiles (cobalt, vermilion, coral, powder blue). This color-blocked masonry functions as both visual index and chromatic artwork in itself. Misusing it by replacing solid saturated backdrops with muted grey containers or busy photo thumbnails immediately degrades it into an ordinary e-commerce grid.
MUST
- Retain strict 16px gutters between moodboard tiles across all asymmetrical grid spans.
- Pair rich, saturated monochrome tiles (pure vermilion, saturated cobalt) with washed pastel neighbours.
- Position micro card labels strictly at top-left and item counts at bottom-left within card bounds.
- Use pill-shaped 999px radiuses exclusively for tags, micro-badges, and filter buttons.
AVOID
- Do not add soft drop shadows to moodboard cards; depth is achieved via solid contrast and flat boundaries.
- Avoid mixed rounded corners—never blend 4px boxy corners with 14px tile radiuses.
- Do not place busy multicolored photos inside small cards; restrict small tiles to single-tone graphics.
- Never use serif body type or decorative script inside the functional canvas.
