IROZOU is a color workspace made for designers: fashion, textile, graphic and product designers who match colors and work with color codes every day. MATCH COLORS FASTER Point your camera at a fabric, sample, or photo, or pick an image, and IROZOU finds the closest colors in your library with a ΔE00 difference value. No more guessing which code is closest. YOUR PROFESSIONAL COLOR LIBRARY Import swatch libraries from internationally recognized color systems and design tools: ASE, ACB, ACO, CSV and JSON. Once you import your own library, IROZOU switches entirely to that data. Every code, search result and palette then comes from the system you actually use for production. 1,995 BUILT-IN REFERENCE COLORS Before you import anything, explore IROZOU's own reference colors: 285 sets of seven, each set one hue from light to dark. Use them for ideas and early drafts. READ EVERY VALUE Each color shows its code, HEX, RGB, Lab, LCh and approximate CMYK. Series are labeled by use: cotton, polyester, leather, metallic, nylon, coated and uncoated print. CHECK CONTRAST Choose text and background colors and see the contrast ratio instantly, with AA guidance. MOODBOARD STUDIO Add photos, images or full PDF pages to a board. Pick colors directly from the board or auto-extract a palette, then arrange swatch capsules. Export a vector CMYK PDF for print, or save JPGs to Photos. MY PALETTES Save palettes, export ASE or CSV for your other design tools, and back up your whole library. PRIVATE BY DESIGN No account. No tracking. Your colors and boards stay on your device. All features are free. Optional one-time support purchases help the developer and do not unlock any features. On-screen colors are a reference. Always confirm production colors with a physical standard. Import only color data you have the right to use. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Support IROZOU | $4.99 | one-time | | Support IROZOU | $6.99 | one-time | | Support IROZOU | $9.99 | one-time | | Support IROZOU | $14.99 | one-time | | Support IROZOU | $19.99 | one-time | | Support IROZOU | $29.99 | one-time | | Support IROZOU | $49.99 | one-time | | Support IROZOU | $59.99 | one-time | | Support IROZOU | $99.99 | one-time | | Support IROZOU | $149.99 | one-time | ## Is IROZOU safe?

IROZOU imports them, removes backgrounds with on-device AI where it finds a clear subject, and arranges a balanced, designer-style moodboard with white space and a color card. Tap again for a fresh arrangement. - One-tap Share: send your board via AirDrop, Messages or Mail. - Pin boards: long-press a board (right-click on Mac) to keep it at the top. - Drag thumbnails to reorder layers. - Cleaner proportion bars with labels on small glass or dark chips. - Better iPhone Duo support: the Dock lines up with the camera and stays in the same place when folded or unfolded. - Images can be enlarged up to twice the board size. - Deleted boards and unused images are fully cleared after 30 days to save space. - Fixed an issue where Done, Delete and Undo could not be tapped after enlarging an image. ### 1.0.2 — 2026-10-22 - Studio is faster and more stable: background removal no longer freezes the board, and large images stay smooth. - Name every new board, set the number of pages, and size custom boards in mm or pixels with your own DPI. - Fill page: make any photo cover the whole board, then drag to choose the crop. - Add to My palettes: save any capsule set from a board as a named palette. - Clearer controls: one-tap buttons for vertical or horizontal capsules, capsules or proportion bar, and light or dark capsules. - Proportion bars now use the same glass look as capsules, in the app and in PDF exports. - Color picker: a new glass pointer shows exactly where you're sampling, and the white balance button is easier to find. White balance set in the live camera now carries over to the captured photo. - Smoother transitions between tabs and boards. - Drag across the tab bar to slide a glass lens between tabs. - Recently deleted boards are now permanently removed after 30 days. - Built-in colors are clearly marked as reference only; import your own swatch library for production color matching. ### 1.0.1 — 2026-10-21 Welcome to IROZOU 1.0. • Live camera color matching with white balance • Search by code, name or HEX value • Achievability check for screen and CMYK print • Color Match with ΔE00 and pass tolerance • Shades, cross-reference and color vision preview • Studio: unlimited boards, background removal, proportion bars, redo and Apple Pencil support • 1,995 built-in reference colors, or import your own library • iCloud sync, widgets and share extension • Designed for iPhone, iPad, Mac and Apple Vision Pro ### 1.0 — 2026-10-21 No release notes. ## More apps by Yu Hsuan Weng - [Koiden](https://appshunter.io/ios/app/koiden/id6791394237) All apps by Yu Hsuan Weng: https://appshunter.io/developer/6791394239 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
