The color #280FA5, a deep blue-purple hue, presents accessibility challenges, particularly regarding text contrast. When used as a background color, ensure that text displayed on top of it is a light color, such as white or a very pale yellow, to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio (minimum 4.5:1 for normal text and 3:1 for large text). Insufficient contrast can make content difficult or impossible for users with low vision or color blindness to read. Avoid pairing #280FA5 with other dark colors as this will exacerbate the problem. Consider using a contrast checker tool to verify compliance. Furthermore, when using this color to convey meaning (e.g., in charts or graphs), provide alternative textual cues or patterns to ensure that the information is accessible to all users, including those who cannot distinguish colors.
