What This Tool Does

A color conversion and manipulation utility for working with colors across multiple formats used in web development, graphic design, and user interface design. It features a smart color parser that accepts input in any common format including hexadecimal codes with or without hash prefix in both short and long forms, RGB functional notation, HSL functional notation, comma-separated RGB values, and over 140 CSS named colors like coral, steelblue, and papayawhip. Format conversion functions translate between hex, RGB, and HSL color spaces with full component extraction for programmatic use. Color manipulation operations include finding complementary colors by rotating 180 degrees on the color wheel, darkening and lightening by adjustable percentages through lightness modification, inverting colors by subtracting each channel from 255, and adjusting saturation up or down for more vibrant or muted tones. The random color generator produces full color specifications across all formats, while the palette generator creates harmonious color schemes using color theory principles including analogous, complementary, and evenly-distributed hue rotations with subtle saturation and lightness variations. All operations return results in multiple formats simultaneously for immediate use in CSS, design tools, or further processing.

Product Instructions

Color Adjustment - Instructions

Overview

Color Adjustment provides color format conversion, manipulation, and generation utilities. It accepts colors in multiple formats (hex, RGB, HSL, named colors) with automatic format detection, and performs conversions, adjustments, and palette generation.

Accepted Color Formats

The color parameter accepts any of the following formats -- the parser auto-detects:

  • Hex: #3498db or 3498db (with or without #, 3 or 6 digits)
  • RGB function: rgb(52, 152, 219)
  • HSL function: hsl(204, 70, 53)
  • Comma-separated RGB: 52,152,219
  • Named color: red, forestgreen, dodgerblue, etc. (all standard CSS/HTML color names)

Actions

  • Optional: none

Example:

{ "action": "color-name-to-hex", "color": "forestgreen" }
Manipulations
color-complement

Get the complementary color (opposite on the color wheel, 180-degree hue rotation).

  • Required: color -- the base color
  • Optional: none

Example:

{ "action": "color-complement", "color": "#FF0000" }
color-darken

Darken a color by reducing its lightness.

  • Required: color -- the color to darken

Example:

{ "action": "color-darken", "color": "#3498db", "amount": 20 }
color-lighten

Lighten a color by increasing its lightness.

  • Required: color -- the color to lighten
  • Optional: amount -- percentage to lighten (1-100, default: 10)

Example:

{ "action": "color-lighten", "color": "navy", "amount": 15 }
color-invert

Invert a color (each RGB channel becomes 255 minus its value).

  • Required: color -- the color to invert
  • Optional: none

Example:

{ "action": "color-invert", "color": "#3498db" }
color-saturate

Increase a color's saturation.

  • Required: color -- the color to saturate

Generators
color-random

Generate a random color. Returns hex, RGB, and HSL values.

  • Required: none
  • Optional: none

Example:

{ "action": "color-random" }
color-palette-generate

Generate a harmonious color palette. Uses analogous colors for small palettes (up to 3), pentagon distribution for medium palettes (up to 5), and even distribution for larger palettes.

  • Required: none
  • Optional: count -- number of colors to generate (1-20, default: 5)

Example:

{ "action": "color-palette-generate", "count": 8 }

Common Workflows

  1. Brand color exploration: Use color-name-to-hex to start from a named color, then color-complement to find a contrasting accent, and color-lighten / color-darken to create variants.
  2. Building a UI palette: Use color-palette-generate with a desired count, then fine-tune individual colors with color-saturate or color-desaturate.
  3. Format conversion for developers: Convert between hex, RGB, and HSL using the conversion actions to match the format required by your CSS, design tool, or API.
  4. Accessibility checks: Use color-lighten and color-darken to create sufficient contrast between text and background colors.

Important Notes

  • All actions except color-random and color-palette-generate require the color parameter.
  • The amount parameter only applies to color-darken, color-lighten, color-saturate, and color-desaturate.
  • The count parameter only applies to color-palette-generate.
  • All responses include the result in multiple formats (hex, RGB, and/or HSL) for convenience.
  • Named colors support all 147 standard CSS/HTML color names (e.g., aliceblue, coral, midnightblue, tomato).

Live Schema And Examples

Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

  • Exact schema: call agentpmt-tool-search-and-execution with action: "get_schema", and tool_id: "color-adjustment".
  • Detailed examples: call agentpmt-tool-search-and-execution with action: "get_instructions" and tool_id: "color-adjustment", or call this product with action: "get_instructions" when the product tool is already selected.
  • Treat returned live schema and instructions as more specific than this generated summary.
