What is a design theme system?

A design theme system is a collection of consistent visual elements including colors, typography, spacing, and other design tokens that create a cohesive look and feel across an application or website.

How do I create an effective color scheme?

Start with primary and secondary colors that reflect your brand. Add neutral colors for text and backgrounds. Ensure sufficient contrast for accessibility. Include semantic colors for success, warning, and error states. Test in both light and dark modes.

What's the importance of spacing in design?

Consistent spacing creates visual hierarchy, improves readability, and helps users understand relationships between elements. A spacing scale based on a common ratio (like 4px or 8px) helps maintain consistency across your design.

How do I implement dark mode effectively?

Design your dark theme colors to reduce eye strain, maintain sufficient contrast, and ensure readability. Avoid pure black backgrounds, use slightly muted colors, and test all interactive states. Consider using CSS custom properties for easy theme switching.
