The hex color #013a5d, also known as Astronaut Blue, presents some accessibility challenges. Its low luminance value means that it requires careful consideration when used as a foreground or background color, especially concerning text. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. For normal text (14pt/18px and larger), a contrast ratio of at least 4.5:1 is recommended, while for large text (18pt/24px and larger), a ratio of 3:1 is required. When using #013a5d, ensure the accompanying text or elements have a light enough color to meet these contrast ratios. Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey information, as colorblind users might miss it. Use other visual cues, such as icons or text labels, in conjunction with color.
