Getting Started

Access colorStudio

Visit colorStudio in your browser. No installation required - it's a fully functional web application.

Interface Overview

The colorStudio interface is organized into several key sections:

  1. Color Controls: Base color selection and harmony types
  2. Generated Palette: Color swatches with accessibility indicators

  4. Gradient Display: Real-time gradient preview and stop management
  5. Basic Analysis: WCAG compliance and accessibility metrics
  6. Saved Palettes: Manage and organize your color schemes

Palette Generation

Creating Your First Palette

  1. Select a Base Color: Use the color picker to choose your starting color
  2. Choose a Harmony: Select from complementary, triadic, analogous, or other harmony types
  3. Generate: Click "Generate Palette" to create your color scheme
  4. Review: Check the accessibility indicators for each color
/* Example generated palette */
:root {
  --primary: #3b82f6;      /* ✅ AAA - Excellent contrast */
  --secondary: #8b5cf6;    /* ✅ AA - Good contrast */
  --accent: #06b6d4;       /* ✅ AAA - Excellent contrast */
  --success: #10b981;      /* ✅ AAA - Excellent contrast */
  --warning: #f59e0b;      /* ⚠️ AA - Good contrast */
  --error: #ef4444;        /* ✅ AAA - Excellent contrast */
}

Harmony Types

colorStudio supports multiple color harmony types:

  • Complementary: Colors opposite on the color wheel
  • Triadic: Three colors evenly spaced around the color wheel
  • Analogous: Colors adjacent to each other on the color wheel
  • Split Complementary: A base color and two colors adjacent to its complement
  • Tetradic: Four colors forming a rectangle on the color wheel
  • Monochromatic: Variations of a single hue

Accessibility Analysis

Every generated color includes real-time accessibility analysis:

  • WCAG 2.1 AA Compliance: Pass/fail status with actual contrast ratios
  • APCA Scores: Advanced Perceptual Contrast Algorithm for more accurate results
  • Color Blindness Simulation: Preview how colors appear to users with color vision deficiencies
  • High Contrast Mode: Test compatibility with high contrast accessibility settings

Gradient Generation

Creating Beautiful Gradients

colorStudio's gradient engine supports three types of gradients:

1. Linear Gradients

background: linear-gradient(45deg, #3b82f6, #8b5cf6, #06b6d4);

2. Radial Gradients

background: radial-gradient(circle, #3b82f6, #8b5cf6);

3. Conic Gradients

background: conic-gradient(from 0deg, #3b82f6, #8b5cf6, #06b6d4, #3b82f6);

Gradient Stop Management

  • Add Stops: Click the "+" button to add new color stops
  • Remove Stops: Click the "×" button to remove stops
  • Adjust Position: Drag stops or use the position input
  • Color Picker: Click any stop to open the color picker
  • Hover Actions: Use FG/BG buttons for quick foreground/background testing

Gradient Accessibility

colorStudio analyzes gradient accessibility by:

  • Multi-point Contrast Analysis: Testing contrast at multiple points along the gradient
  • Background Compatibility: Ensuring gradients work with common background colors
  • Text Readability: Verifying text remains readable over gradient backgrounds
  • WCAG Compliance: Checking overall accessibility compliance

Best Practices

1. Start with Accessibility

Always begin your color design process with accessibility in mind:

  • Choose colors that meet WCAG 2.1 AA standards
  • Test against multiple backgrounds
  • Consider color blindness and visual impairments
  • Use high contrast for important elements

2. Create Semantic Color Systems

Organize your colors by purpose, not appearance:

/* Good: Semantic naming */
:root {
  --color-text-primary: #1f2937;
  --color-text-secondary: #6b7280;
  --color-background: #ffffff;
  --color-surface: #f9fafb;
  --color-border: #e5e7eb;
}

/* Avoid: Appearance-based naming */
:root {
  --color-dark-gray: #1f2937;
  --color-light-gray: #6b7280;
  --color-white: #ffffff;
}

3. Test Multiple Contexts

Always test your colors in different contexts:

  • Light and dark themes
  • Different background colors
  • Various text sizes and weights
  • Different devices and screen sizes

4. Document Your Decisions

Keep track of your color choices:

  • Save palettes with descriptive names
  • Document accessibility scores
  • Note any special considerations
  • Share with your team

Troubleshooting

Common Issues

Q: Colors aren't generating properly A: Ensure you've selected a valid base color and harmony type. Try refreshing the page if issues persist.

Q: Accessibility scores seem incorrect A: Check that you're testing against the right background colors. Use the hover actions to test different combinations.

Q: Export isn't working A: Ensure you have a valid palette or gradient generated. Try refreshing the page and regenerating.

Q: Gradient stops aren't updating A: Make sure you've selected a stop before making changes. Use the color picker or position input for precise control.

Performance Tips

  • Large Palettes: Keep palette sizes reasonable for better performance
  • Complex Gradients: Limit the number of stops for smoother rendering
  • Browser Compatibility: Use modern browsers for the best experience
