The hex color #273B71, also known as Astronaut, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of 8.7 cd/m² results in a low contrast ratio against a white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability. Using #273B71 for text on a white background may not meet these guidelines, potentially making it difficult for users to distinguish the text from the background. To improve accessibility, consider pairing #273B71 with lighter colors or using it for larger design elements where the contrast is less critical. Alternatively, using a darker background color can create a more accessible contrast ratio. When using it for interactive elements, ensure sufficient visual cues beyond color alone are present to aid users who may have difficulty distinguishing colors.
