The color #21353D, also known as Outer Space, presents some accessibility challenges, especially when used for text. Its low luminance value of approximately 5% means that text rendered in this color requires very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text to meet AA standards. When using #21353D as a background, ensure that text colors like white (#FFFFFF) or very light grays are used. Tools such as contrast checkers can help verify compliance. For decorative elements, the contrast requirements are lower, but still consider users with visual impairments. Avoid using #21353D for crucial UI elements without proper contrast as it can render the content invisible to many users. Remember to test your color choices with real users to ensure usability.
