The color #15082D, also known as Black Rock, presents significant accessibility challenges, especially concerning color contrast. When used as a background, text needs to be very light (e.g., white or light yellow) to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG guidelines. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color to convey crucial information without providing alternative visual cues, like icons or text labels, to support users with color vision deficiencies. Ensure interactive elements, such as links or buttons, have sufficient contrast in their different states (hover, focus, active) to be easily identifiable.
