Due to its relatively dark nature, it necessitates careful consideration of contrast ratios to ensure readability for all users, including those with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text to be easily distinguishable from its background. For normal text (14pt/18px and below), a contrast ratio of at least 4.5:1 is recommended, while for large text (18pt/24px and above) it suggests a contrast ratio of 3:1. When using #1F2979 for text, it is essential to pair it with a light-colored background to meet these requirements. A tool like a contrast checker can assist in determining if the chosen color combination provides adequate contrast. Avoid using it for small text or detailed graphics against dark backgrounds, as this can cause eye strain and make content inaccessible. Remember that adhering to accessibility standards broadens your audience and enhances the user experience for everyone.
