The color #01385D, also known as Astronaut Blue, presents considerable accessibility challenges. Its low luminance value of 0.01 necessitates careful consideration of contrast ratios, especially for text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. Using #01385D as a background color demands very light text colors to meet these standards. For instance, white text (#FFFFFF) provides a contrast ratio of approximately 16.8:1, which is excellent. However, slightly darker shades of grey might fall below the required threshold, causing readability issues for users with visual impairments. Ensuring sufficient contrast is crucial for users with low vision or color blindness, and tools like contrast checkers should be used to validate compliance with accessibility standards. Additionally, avoid using this color for critical UI elements without proper contrast, as it can hinder usability.
