The hex color #003c5d, also known as Astronaut Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using a lighter color for text on an Astronaut Blue background is crucial. White or very light shades of gray or yellow can dramatically improve readability. Tools like contrast checkers are invaluable for verifying compliance and optimizing color choices. For users with visual impairments, including those with low vision or color blindness, adequate contrast is essential for perceiving content effectively. Therefore, always prioritize accessibility by testing color combinations thoroughly.
