Acid Green
#cafc00Brand accent — the singular chromatic highlight. Marks the Pro Access pill in the nav, the primary upgrade button, and occasional pill highlights. The only color allowed to carry brand meaning at full saturation
Craftwork is a clean, light-canvas marketplace language built on near-monochrome neutrals — white cards on #f9f9f9 paper, deep black text, hairline gray borders — with one acid-green (#cafc00) accent that acts as a visual highlighter for premium and brand moments. A geometric humanist sans (Euclid Circular A) carries the typography, running from whisper-tight 72px display headlines (ls ≈ -0.069em) down to compact 14–16px body text, creating a density that feels editorial rather than spacious. Components sit lightly on the surface: 10px rounded cards, 9999px pill nav buttons, and shadows so subtle they read as paper texture rather than elevation. The remaining two accents — vermillion #f54911 and magenta #c42df9 — appear only as decorative punctuation in icons, tags, and illustration, never competing with the green for attention. The overall rhythm is compact and content-forward, prioritizing catalog density over generous white space.
#cafc00Brand accent — the singular chromatic highlight. Marks the Pro Access pill in the nav, the primary upgrade button, and occasional pill highlights. The only color allowed to carry brand meaning at full saturation
#f54911Secondary accent — warm red-orange for emphasis text, decorative borders, and small brand moments. Never used for backgrounds at scale
#c42df9Tertiary accent — vivid pink for icons, decorative strokes, and illustration pops. Functions as a tertiary tag color in the brand palette
#000000Primary text, heading strokes, and the dominant interface color. Carries body copy, icons, and high-contrast borders
#0d0d0dDark surface fill for active states, dark buttons, and inverted sections
#1e1e1eSecondary dark surface — slightly softer than Obsidian for cards that need depth without going fully black
#14151aNear-black for specific UI borders and text where pure black reads too harsh against warm grays
#606060Secondary text, muted icons, and secondary button text. The workhorse mid-gray for body copy that should recede
#999999Tertiary text, placeholder copy, and disabled icon strokes
#9ea0a8Cool-leaning gray for subtle borders and muted helper text
#f9f9f9Page canvas — the dominant background across the entire site. Slightly warm, never pure white
#f2f2f2Secondary surface for inset panels, section dividers, and soft background washes
#ffffffLight supporting surface for subtle backgrounds and section separation. Do not promote it to the primary CTA color
#dee0e3Hairline borders, dividers, and input outlines. The thinnest structural line in the system

The single typeface across the entire system. Euclid Circular A is a geometric humanist sans with wide apertures and circular geometry — it reads modern but warm, which keeps a design-marketplace brand from feeling cold. Used for everything from 11px nav labels to 72px display headlines. The negative letter-spacing pattern (tightest at -0.069em for 72px, loosening to 0 at 11px) creates a deliberate density that defines the site's editorial rhythm.

Elevation is whisper-quiet — the dominant shadow pattern uses a cool purple-gray (47, 43, 67) at only 10% opacity, combined with a hairline inset top border. The result is depth that reads as paper layering, not digital UI elevation. Cards never float dramatically; they sit on the surface with the subtlety of printed matter.

Max-width 1200px centered, with a generous hero that breaks the content width for full-bleed display typography. The hero is a centered stack: logo mark → display headline → subtitle → CTA pair. Sections below alternate between content bands and social-proof bands (company logo wall) without alternating light/dark contrast — everything stays on Paper canvas. Category navigation uses a full-width segmented tab bar, followed by a centered row of filter pills. The catalog grid is 4-column on desktop (UI kit, Mockup, Icon, Inspiration tiles), collapsing to 2-3 columns on smaller screens. Testimonials use a 3-column masonry layout. Vertical rhythm is compact (40-64px section gaps) but the hero and CTA sections open up to 80-120px padding to create breathing room around the most important content. Navigation is a single sticky top bar — no sidebar, no mega-menu.
Imagery is catalog-forward: colorful product previews (UI kits, mockups, font specimens) displayed inside rounded card frames. The cards themselves are neutral — white or paper — letting the illustrated previews carry the color. Decorative illustrations in the hero and section dividers use the full three-color accent palette (acid green, vermillion, magenta) at low saturation as soft radial gradient washes. No photography of people or environments; the site is entirely iconography, product crops, and brand-colored illustration. Iconography is outlined at ~1.5-2px stroke, monochrome black or accent-colored, with geometric simplicity matching the typeface.

Gradients are used sparingly as soft background washes to add atmospheric depth without introducing new color tokens. The pattern is always a radial fade from a desaturated green-tinted translucent fill to fully transparent — never a multi-color gradient. - **Hero wash**: radial-gradient(80% 60% at 55% 5%, rgba(180,235,160,0.45), transparent) — soft lime glow from the top-center - **Section wash A**: radial-gradient(70% 80% at -5% 75%, rgba(180,235,160,0.35), transparent) — corner glow from bottom-left - **Section wash B**: radial-gradient(circle at 45% 45%, rgba(200,250,190,0.25), transparent 55%) — centered diffused glow These washes sit on the Paper canvas and should never appear on card surfaces or over text content. They define the mood of hero and transition sections only.
