By following accessibility standards, you make your content more accessible and user-friendly, enhancing the overall user experience.
Importance Color Contrast is Used
Screen Reader Users: Poor color contrast can hinder readability for screen reader users, making content harder to comprehend.
Cognitive Disabilities: High color contrast aids users with cognitive disabilities in quickly identifying key information and improving focus.
Improving Readability: Ensuring sufficient contrast between text and background, along with using additional cues like text labels or patterns, helps enhance clarity and accessibility for all users.

Follow WCAG Guidelines
To comply with accessibility standards, text must meet the following contrast ratio requirements:
- Regular Text (body text, captions, small headings): A minimum contrast ratio of 4.5:1 is required for readability by most users.
- Larger Text (at least 18-point or 14-point bold): Larger text is easier to read, so, it requires a lower contrast ratio of 3:1 to meet accessibility standards.
Failure to meet these standards may make text difficult for users with visual impairments to perceive.
