It is important to consider the contrast and readability factors when using this color in designs.

The hex color #1F21C7, also known as Persian Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value means that text rendered in this color against a white background may not meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To ensure accessibility, it's crucial to pair this color with much lighter hues, such as white or very pale yellows. Using tools to check color contrast ratios is highly recommended during the design process. Alternatively, consider using this color sparingly for decorative elements rather than for essential textual information. Providing alternative styling options for users can further improve accessibility.
