The color #150AAA, a deep shade of ultramarine, presents accessibility challenges. Its low luminance value of 0.038 necessitates careful consideration for text and interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against a background. Using #150AAA as a background color requires very light text colors like white (#FFFFFF) or very light grays to ensure sufficient contrast. Without adequate contrast, users with low vision or color blindness may struggle to read the content. Tools like contrast checkers can accurately assess the contrast ratio between foreground and background colors. Also, avoid using #150AAA to convey essential information without providing alternative cues, such as labels or icons, as colorblind users may not perceive it correctly. Thoughtful design practices ensure inclusivity and optimal user experience.
