The color #2A3871, also known as Astronaut, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, sufficient contrast with foreground text is essential to ensure readability for individuals with visual impairments. A light color, such as white or a very pale yellow, would be suitable for text. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools like WebAIM's Contrast Checker can help verify contrast ratios. When used for interactive elements like buttons or links, consider providing additional visual cues, such as changes in color or the addition of an underline upon hover or focus, to assist users with cognitive disabilities or those who rely on keyboard navigation. Ensure that any color combinations meet accessibility standards to provide an inclusive experience for all users.
