Hue Vault 2.0 is a complete pro upgrade — and a one-time purchase, no subscription. DESIGN-SYSTEM GENERATOR Turn any color into a full, production-ready scale: a Tailwind 50–950 ramp and a Radix-style 12-step scale with proper roles (backgrounds, borders, solids, text), a matching neutral ramp, and semantic success/warning/error/info colors — in light and dark. The text steps are tuned to real contrast targets so they actually pass. A PERCEPTUAL ENGINE Harmonies, tints, shades, and scales are now generated in OKLCH (the perceptually-uniform space behind CSS Color 4 and Tailwind v4), so every result is tonally even and never clips out of gamut. ACCESSIBILITY LAB See an N×N contrast grid for your whole palette with both WCAG 2.2 ratios and APCA Lc readability, simulate eight kinds of color-vision deficiency with a severity slider, get flagged on color pairs that collide for color-blind users, and fix any failing pair with one tap. GRADIENT & MESH STUDIO Build perceptually-smooth gradients interpolated in OKLab (no muddy middles), plus mesh gradients on iOS 18 — export as SwiftUI, CSS, or a wallpaper. LIGHT → SHADOW RAMPS Generate temperature-shifted shading ramps for illustration, with a live preview. REAL EXPORTS Design tokens (DTCG), SwiftUI color sets with dark + Display-P3, CSS oklch() with P3, Tailwind, Material, Android, SVG. Plus tags, color search, drag-and-drop, and Shortcuts. Everything runs on-device. No account. No tracking.

Huevault 1.1 - more tools, more color science. TYPE A HEX CODE DIRECTLY Got a color from a brief, a design spec, or a web page? Just type the hex code - #RRGGBB or RRGGBB, with or without the hash - and Huevault commits it the moment it's valid. No more going through the color wheel to enter a value you already know. Works when adding a color to an existing palette and when picking a base color for a new harmony. OKLCH VALUES EVERYWHERE Every swatch now shows its OKLCH value in the inspector - the perceptually uniform color space that powers Tailwind CSS v4 and CSS Color Level 4. OKLCH lightness is the only kind that matches human perception accurately, so equal L values actually look equally bright. Tap to copy. TWO NEW EXPORT FORMATS - Tailwind CSS config - copies a ready-to-paste JS object block (extend.colors format) using oklch() values, matching exactly how Tailwind v4 defines its own palette. Drop it into tailwind.config.js or a @theme block. - OKLCH values - one oklch() CSS value per line, for pasting into any CSS Color Level 4-aware stylesheet. Both join the existing six formats in the "Copy as" menu. --- Also in 1.1 (earlier in this build cycle): TWO NEW HARMONY TYPES - Split Complementary: your base color plus two near-complements (flanking the opposite hue at 30) - high contrast with less visual tension than pure complementary. - Square: four hues perfectly 90 apart on the wheel - diverse yet balanced, and geometrically distinct from the Tetradic rectangle. TINT / SHADE LADDER Tap any swatch in your palette and you'll find a new Tints & Shades section: five tints lightening toward white and five shades deepening toward black, each tap-to-copy. The fastest way to build a complete tonal scale from a single brand color. COLOR-BLIND PREVIEW IN THE SWATCH INSPECTOR The protanopia / deuteranopia / tritanopia preview that was only in the contrast checker is now in the swatch inspector too - so you can see any individual color through each lens, right where you're working. FOUR EXPORT FORMATS - Swift / Xcode JSON - paste directly into an Xcode asset catalog Color Set. - Figma tokens JSON - W3C Design Token format, compatible with Figma Tokens (Tokens Studio) and standard token pipelines. - Android XML - drop into your res/values/colors.xml. - SVG swatches - a row of labeled rectangles you can paste into Figma, Sketch, or any SVG-aware tool. LIBRARY SEARCH A search bar in the Library filters your palettes by name as you type. Handy once you've built up a library. Huevault is still fully offline - no account, no subscription, no tracking. Everything lives on your device.
