The color #003D5D, also known as Astronaut Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #003D5D with darker text colors would likely fail these guidelines, making the content difficult to perceive for users with visual impairments. Therefore, designers and developers must carefully consider text and interactive element colors to achieve adequate contrast. Tools are available to measure contrast ratios. Also, always avoid using this color as the sole method of conveying important information, as users with color blindness may not be able to distinguish it.
