The color #054561, also known as Astronaut Blue, presents significant accessibility challenges. Its low luminance value results in poor contrast against white text, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color falls far short of these recommendations when paired with light backgrounds. To improve accessibility, consider using this color with a much lighter foreground color or a much darker background. Additionally, providing alternative text descriptions for images that use this color is crucial for users who rely on screen readers. Careful consideration of color contrast is essential for creating inclusive and user-friendly web designs.
