The hex color #1B33BB, also known as Persian Blue, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of 0.083 makes it a dark color, which means it requires light-colored text to provide sufficient contrast. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14 points bold or 18 points regular). When using #1B33BB as a background color, ensure that the text color provides adequate contrast to meet these guidelines. Tools like contrast checkers can help verify compliance. Also, consider providing alternative styling options for users who may need to adjust the color scheme for better readability. Avoid using this color for critical information without sufficient contrast.
