HueShift

HueShift is a browser-based application that enables developers and designers to paste any text or code containing color values and instantly see all detected colors in a visual gallery.

Automatically detects hex (#fff, #ffffff), RGB/RGBA, HSL/HSLA, and named colors across multiple formats, preserving the original format during replacement.

Features two replacement modes: Replace All for bulk operations and Selective mode for granular control over specific color instances.

Includes WCAG contrast checker with AA/AAA compliance badges and automatic accessible color suggestions that adjust lightness while preserving hue.

Similar color detection using Delta-E perceptual algorithm identifies unintentional color variations and enables one-click palette consolidation.

Multiple specialized tabs: Colors gallery, Duplicates finder, Color Pairs analysis, Before/After comparison, Palette Generator, and Export options.

Undo/redo history with keyboard shortcuts (Cmd/Ctrl+Z) and resizable panels for customizable workspace layout.

Fully responsive design with mobile-friendly tab navigation and drawer-based inspector panel.

100% client-side processing for privacy - no data leaves the browser.

As a non-frontend developer building side projects with AI tools, I realized color management was becoming a code maintenance problem, not just a design problem.

Finding colors across different formats (hex, RGB, HSL) was tedious - CMD+F for #1a73e8 wouldn't find rgb(26, 115, 232).

Accidentally created multiple near-identical color variations through copy-paste mistakes, leading to design system drift.

Context switching between code editor, color picker, and manual find-replace was killing development flow.

Design tools like Figma were too heavy for simple 'just change this color' tasks, and existing developer tools didn't understand color context.

Built to solve my own workflow problems - if it helps others, that's validation, but I already have my tool.
