The hex color #280ED8, a dark blue hue, presents some accessibility challenges. Its low luminance can make it difficult to read text rendered in this color, especially for users with visual impairments. A contrast ratio check is crucial. For text, a minimum contrast ratio of 4.5:1 against the background is recommended by WCAG (Web Content Accessibility Guidelines). If the background is white (#FFFFFF), #280ED8 fails this test. To improve accessibility, consider using lighter text colors like white or a very light gray on #280ED8, or use #280ED8 on a very light background. Avoid using this color for crucial information or interactive elements without careful consideration of contrast. Tools are available online to check color contrast ratios to ensure compliance with accessibility standards and enhance the user experience for everyone.
