The color #2A4371, also known as Astronaut, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance can result in insufficient contrast with lighter text colors, making it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #2A4371 as a background necessitates careful selection of a text color that meets these contrast requirements. Lighter shades of yellow, white, or bright green might offer sufficient contrast, but should be tested using accessibility tools to ensure compliance. Additionally, avoid using this color for crucial interactive elements like buttons or links without providing clear visual cues and sufficient contrast to distinguish them from the surrounding content. Proper implementation of ARIA attributes can also enhance accessibility for screen reader users.
