Understanding its composition and properties is essential for effectively using #0C138F in diverse applications and achieving desired aesthetic results.

The color #0C138F, also known as Ultramarine, presents accessibility challenges due to its dark hue. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using a color contrast checker is essential to verify that the chosen text color meets these standards. When used for interactive elements like buttons or links, the same contrast considerations apply, and additional visual cues (like underlines or borders) are recommended to help users easily identify and interact with the elements. If this color is used for data visualization, distinctive colors and labels are necessary to differentiate data points effectively. Overall, careful planning and testing are necessary to ensure that content using #0C138F is accessible to all users, including those with visual impairments.
