The hex color #02395B, also known as Astronaut Blue, presents some accessibility challenges, particularly in text-based contexts. Its low lightness value of approximately 2% means that it offers very little contrast against darker backgrounds, making text virtually unreadable. To ensure accessibility, it's crucial to pair this color with significantly lighter shades. White (#FFFFFF) or very light grays are recommended for text to achieve a sufficient contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) minimum requirement of 4.5:1 for normal text and 3:1 for large text. Using contrast checking tools can help verify compliance. Furthermore, avoid using this color for interactive elements without careful consideration of contrast and alternative visual cues, such as icons or underlines, to ensure usability for individuals with visual impairments.
