The hex color #2a5771, also known as Casal, presents some accessibility challenges, especially in text-based applications. Its relatively low luminance value of approximately 0.18 means that it requires careful consideration of contrast ratios. When using #2a5771 as a background color, it is crucial to select a foreground color that provides sufficient contrast to ensure readability for users with visual impairments. A white or light-colored text on a #2a5771 background typically offers better contrast than darker shades. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, it is essential to test color combinations using accessibility tools to verify compliance. Failure to meet these contrast requirements can exclude users with low vision or color blindness. Furthermore, relying solely on color to convey information is not advisable; supplementary cues like text labels or icons should be used to ensure accessibility for all users.
