Creating Custom Color Palettes

Colors are the foundation of any great theme. Power UI provides multiple ways to create harmonious color palettes that work beautifully in your reports.

Method 1: AI-Powered Generation

Simply describe your desired color scheme, and our AI will generate a professional palette:

"Generate a modern palette with navy blue as primary, coral accents, and neutral grays"

Method 2: Figma Import

Already have brand colors in Figma? Import them directly:

  1. 1. Copy your Figma file URL
  2. 2. Click "Import from Figma" in Power UI
  3. 3. Paste the URL and authenticate
  4. 4. Select color styles to import

Method 3: Manual Creation

Data Colors

Used for chart series, should be visually distinct

Neutral Palette

For backgrounds, borders, and text

Pro Tip: Ensure your colors have sufficient contrast for accessibility. Power UI automatically checks WCAG compliance as you design.

Typography and Text Styling

Consistent typography creates hierarchy and improves readability across your reports. Power UI lets you define text styles once and apply them everywhere.

Text Class Hierarchy

Title Text

Large, bold text for report and visual titles

Size: 16-20px | Weight: 600-700

Header Text

Section headers and important labels

Size: 14-16px | Weight: 500-600

Label Text

Axis labels, data labels, and general text

Size: 10-12px | Weight: 400

Callout Text

Small annotations and secondary information

Size: 8-10px | Weight: 400

Font Selection Best Practices

  • Stick to System Fonts: Use Segoe UI, Arial, or Helvetica for maximum compatibility
  • Limit Font Families: Use maximum 2 font families (one for headers, one for body)
  • Maintain Hierarchy: Use size and weight to create clear visual hierarchy
  • Consider Context: Smaller fonts for dense dashboards, larger for presentations

Advanced Visual Customization

Power UI goes beyond basic styling to offer granular control over every visual type in Power BI. Create themes that handle edge cases and special requirements.

Visual Variants

Create multiple style variations for different use cases:

  • Default: Standard appearance
  • Emphasis: Highlighted visuals
  • Subtle: Background elements
  • Custom: Special purpose styles

Per-Visual Settings

Customize each visual type independently:

  • • Column & Bar Charts
  • • Line & Area Charts
  • • Tables & Matrices
  • • Cards & KPIs

Example: Custom Card Styling

"card": {
  "*": {
    "labels": [{
      "fontSize": 24,
      "fontFamily": "Segoe UI",
      "color": { "solid": { "color": "#1a1a1a" } }
    }],
    "categoryLabels": [{
      "fontSize": 12,
      "color": { "solid": { "color": "#666666" } }
    }],
    "background": [{
      "color": { "solid": { "color": "#f8f9fa" } },
      "transparency": 0
    }],
    "border": [{
      "show": true,
      "color": { "solid": { "color": "#e9ecef" } },
      "radius": 8
    }]
  }
}
