The hex color #2B3770, also known as Astronaut, presents some accessibility considerations for web design. Its relatively dark hue may pose challenges when used as a background color, particularly concerning text legibility. To ensure optimal readability, it is crucial to pair #2B3770 with light-colored text, such as white or a very pale yellow. The contrast ratio between the text and background should adhere to WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Using contrast checker tools can help verify compliance. Furthermore, consider users with visual impairments by providing alternative styling options, such as high-contrast themes. Avoid using #2B3770 as the sole means of conveying important information; instead, supplement it with textual cues or icons to cater to users who may have difficulty distinguishing colors.
