The color #1F4079, also known as Astronaut, presents some accessibility challenges, especially for users with visual impairments. Its low luminance value of approximately 0.056 results in poor contrast against a standard white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #1F4079 fails to meet these standards when paired with white. To improve accessibility, consider using lighter shades of text or interface elements against this color. Alternatively, implementing a high-contrast theme option would greatly benefit users who need enhanced visibility. It is crucial to test color combinations with accessibility evaluation tools to ensure compliance and inclusivity for all users. Another way to improve readability is increasing the font size or use bold text.
