This color is often associated with royalty, wisdom, and tranquility, making it a popular choice for branding and design where these qualities are desired. Its unique shade makes it stand out, but accessibility considerations are crucial when using it in digital applications.

The hex color #181088, also known as Ultramarine, presents significant accessibility challenges, especially when used as a text color on a white or light-colored background. Its low luminance results in poor contrast, making it difficult for individuals with visual impairments to read the text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine often falls short of these recommendations. To improve accessibility, consider using a lighter text color such as white (#FFFFFF) or a very light gray when Ultramarine is used as a background. Alternatively, if Ultramarine is used for text, pair it with a much lighter background color to ensure sufficient contrast. Tools like contrast checkers can assist in evaluating and adjusting color combinations to meet accessibility standards. Always prioritize readability and inclusivity to provide a better user experience for everyone.
