Common Calculations & Examples

Example 1: Creating a Custom Color Palette

Problem: Collect and organize colors for a design project

Steps:

  1. Browse palettes and click colors you like
  2. Check HEX, RGB, and HSL values
  3. Click "Save to My Palette" for colors to use
  4. Reference your saved palette when coding
Result: Custom palette with saved colors ready for your project

Explanation: Save colors to create a reference library that persists in your browser. Use HEX codes in CSS, RGB for design software, or HSL for creating color variations.

Example 2: Converting Between Color Formats

Problem: Get HEX, RGB, and HSL values for different applications

Steps:

  1. Select or enter a color
  2. View the color information panel
  3. Copy the format you need (HEX for CSS, RGB for design software, HSL for variations)
Result: HEX: #4A90E2, RGB: (74, 146, 226), HSL: (210°, 74%, 59%)

Explanation: The tool automatically converts between all three formats. HEX is standard for web CSS, RGB for image editing, and HSL for creating color variations.
