Color Tool Download

Purpose & User Intent: The tool solves the need to quickly convert a source color into multiple representations and to assemble color palettes for design systems. Primary users are designers, front-end developers, brand managers, and accessibility analysts who work with color consistency across platforms. It enables offline or online workflows and supports designers who need repeatable color data during branding or UI theming.
Core Logic & Features: Core capabilities include color format parsing (hex, rgb, hsl), color space conversions (rgb↔hex↔hsl↔cmyk), and palette generation with configurable size and schemes. Required features are accurate conversions and palette generation; optional features include contrast checks, multiple export formats, and batch processing. Advanced users can choose schemes (analogous, complementary, triadic) and apply perceptual adjustments for accessibility.
Inputs & Outputs: Inputs include source_color (string, hex/rgb, required), target_spaces (array, optional, default [rgb,hex,hsl]), palette_size (int 2–12, optional), output_format (string, optional), include_contrast (boolean, optional). Outputs are converted_colors (array of {hex,rgb,hsl,cmyk}), palette (exportable in JSON or CSS variables), and a download_link.
Algorithms & Calculations: Uses standard sRGB to XYZ to LAB/CMYK conversions with D65 white point; converts between hex, rgb, hsl with established formulas; palette generation uses evenly spaced hue sampling or perceptual schemes.
Error & Edge Cases: Invalid color input yields error codes and no results; palette_size bounds enforce sensible ranges; unsupported target spaces or formats trigger clear technical errors; offline operation defaults to single-color export.
Industry/Region & Localization: Adheres to sRGB as default color space; WCAG contrast guidelines for evaluative checks; no currency or locale dependencies but supports localization of unit labels for advanced users.
Assumptions & Exclusions: Assumes standard sRGB input; excludes design mockups, font handling, or typography tools; not a full design editor.
