Subheading Example

This is a sample paragraph demonstrating how body text appears with your selected color combination. Good contrast ensures readability for all users, including those with visual impairments.

Small text like captions and footnotes require higher contrast ratios to remain legible. This is where WCAG guidelines become especially important.
