Color Tool AI

Color Tool AI analyzes colors for web design and branding tasks by providing precise conversions, contrast evaluation, and palette generation. It accepts hex, rgb, and hsl inputs, normalizes them to a canonical internal representation, and returns consistent outputs suitable for CSS, design systems, and asset pipelines. The tool targets designers, front-end developers, accessibility specialists, brand managers, and marketing teams who must ensure text readability on colored backgrounds, create accessible palettes, and maintain brand color consistency across pages. It supports rapid checks across multiple contexts, including body text, headings, buttons, and overlays, to support real-world UI decisions. Use cases include color audits, theme creation, and client-ready deliverables with quantitative accessibility data.

Conceptually, the tool combines color theory with WCAG-compliant mathematics. It computes relative luminance using sRGB gamma correction, derives contrast ratios between foreground and background colors, and classifies results as pass/fail or AA/AAA based on the selected thresholds. It can generate palettes using established schemes (complementary, analogous, triadic, monochrome) and produce export-ready color tokens such as CSS variables or JSON arrays. All operations are deterministic and suitable for automation in build pipelines, design reviews, and continuous delivery of accessible UI components.

Inputs & Outputs include multiple color entries and a choice of operation. For conversions, each input color is returned in the requested formats (hex, rgb, hsl). For contrast, numbers are provided with two decimal places and an accessibility label. For palettes, arrays of color codes are supplied along with suggested harmony notes. Outputs are designed for direct integration into code, style sheets, or design documentation.

Algorithms & Calculations: Core calculations implement sRGB to linearization, relative luminance, and contrast ratio (L1+0.05)/(L2+0.05) following WCAG guidelines. Color-space conversions cover hex↔RGB↔HSL with standard transformation equations. Palette generation uses common color theory rules with perceptual spacing considerations.

Error & Edge Cases: The tool handles invalid color strings with parsing errors, out-of-range components by clamping, and missing inputs with explicit error codes. Unsupported formats produce conversion errors. Large datasets are processed with clear per-item reporting.

Industry/Region & Localization: Adheres to WCAG 2.1 color contrast guidelines and uses the sRGB color space by default. Outputs are expressed in hex or rgb/hsl, consistent with web standards. No currency or locale-specific units apply.

Assumptions & Exclusions: Assumes on-screen display in sRGB; excludes print color management and ICC profiling. UI styling decisions are outside scope; focus is on color mathematics and data outputs.
