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.

"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. Copy your Figma file URL
- 2. Click "Import from Figma" in Power UI
- 3. Paste the URL and authenticate
- 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" } }
