A hue shift rotates the base color spectrum angle (0° to 360° or -180° to +180° on the HSL color wheel) of an image or color swatch while preserving its original brightness (lightness) and saturation values.

No. Telekit's Hue Shift Generator processes all graphics using HTML5 Canvas GPU acceleration entirely inside your web browser memory. Zero files, image blobs, or colors are ever uploaded, stored, or logged remotely.

You can upload PNG, JPG, JPEG, WebP, SVG, GIF, and AVIF files. You can export the shifted image directly in Lossless PNG, Modern WebP, or Compressed JPEG with adjustable compression quality.

Yes. You can click the '📋 Paste Image from Clipboard' button or press Ctrl+V anywhere in the workspace to instantly load an image from your clipboard without saving it to disk first.

The VisualSplitter component renders the original source and shifted output simultaneously, allowing you to drag an interactive divider handle horizontally to visually verify color transitions across fine details.

In the Color Swatch & Harmonies tab, entering any HEX or HSL color automatically generates 5 classical design harmony schemes: Complementary (180°), Analogous (±30°), Triadic (120° / 240°), Split-Complementary (150° / 210°), and Tetradic (90° / 180° / 270°) with 1-click downloads for JSON, CSS Variables, and SVG palette graphics.

Click the '💻 API Code' button (or press Alt+S) to access copy-ready hue rotation code and standalone script downloads across 6 stacks: CSS filter hue-rotate (.css), HTML5 2D Canvas JS (.js), Node.js Sharp (.ts), Python Pillow (.py), SVG feColorMatrix filter (.svg), and Tailwind CSS design tokens (.tokens.css).

The Instant Tone Presets toolbar offers 1-click filter formulas including Invert 180° (complementary spectrum), Monochrome Grayscale (0% saturation), Vintage Sepia (warm antique nostalgia), Sunset Gold (+35° hue, +35% sat), Cool Cyberpunk (-80° hue, +40% sat), and Vivid Boost (+50% sat, +10% bright) to quickly restyle artwork and test game textures.

The tool calculates relative luminance under the W3C WCAG 2.1 specification to verify contrast against pure black (#000000) and pure white (#ffffff), displaying dynamic pass/fail badges for normal text AA (≥4.5:1) and AAA (≥7.0:1) compliance.

Press Alt+V to toggle between a 2-Column Side-by-Side Split Studio (controls on the left, live canvas or swatch palette on the right) and a Full-Width Stacked layout. Your preference is automatically persisted across sessions in localStorage. Other hotkeys include 'Alt+P' for DevToys Smart Clipboard Auto-Detect, 'Alt+D' to toggle Star favorite bookmark, 'Alt+1' through 'Alt+6' for 1-click quick format copies, '/' for file upload, 'Ctrl+V' to paste image, 'Alt+S' for code snippets, 'Alt+K' or '?' for the shortcuts guide, 'Alt+R' for randomize, 'Alt+I' for 180° invert, 'Ctrl+Enter' to download, and 'Esc' to reset.
