The hex color #1f2d79, also known as Astronaut, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance of 7.34 cd/m² means that it requires careful consideration when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt). When pairing #1f2d79 with white (#ffffff), the contrast ratio is approximately 9.63:1 which passes the AA and AAA levels. However, when paired with black (#000000), the contrast ratio is only 2.18:1, failing accessibility standards. Therefore, it is essential to use lighter colors for text or interface elements on a #1f2d79 background to ensure readability and accessibility for users with visual impairments. Consider using a color contrast checker to verify compliance with WCAG guidelines before finalizing color choices in your design.
