General Information about #0A0890 (Ultramarine)

The hexadecimal color #0A0890, also known as Ultramarine, is a dark shade of blue, specifically belonging to the blue-violet color family. It is composed of 3.92% red, 3.14% green, and 56.47% blue.

The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from the precious stone lapis lazuli, imported from faraway lands. This color is often associated with feelings of calmness, intelligence, and authority. In web design and other creative fields, it is essential to consider its low luminance value when choosing text and background colors to ensure optimal readability and accessibility.

The hex color #0A0890, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its extremely low luminance of approximately 0.007 makes it difficult to read against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color will likely fail these contrast tests against most common background colors, necessitating careful consideration. To improve accessibility, consider using a much lighter text color such as white or very light gray, and rigorously test the contrast ratio using online tools. Alternatively, avoid using this color for text altogether and reserve it for decorative elements where readability is not critical. Enhancements like text shadows or outlines can also help, but should be used cautiously as they may not fully compensate for insufficient contrast. Remember that prioritizing accessibility ensures that your content is usable by a wider audience, including individuals with visual impairments.
