Its dark nature means that it requires careful pairing with contrasting colors to ensure readability for all users, including those with visual impairments.

For text, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against the background. Using a color contrast checker is highly advisable to verify compliance. Moreover, avoid relying solely on color to convey important information, as this excludes individuals with color blindness. Instead, supplement color cues with text labels, icons, or patterns to ensure equitable access to content. Thoughtful design choices enhance usability and inclusivity.
