General Information about Ultramarine

Ultramarine, represented by the hex code #0A0A91, is a deep blue color with a rich history. It originates from the pigment derived from the mineral lapis lazuli, which was highly valued in ancient times and used in paintings and other art forms. Its name literally means 'beyond the sea,' referring to its origin from overseas sources. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a more affordable price. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, serenity, and sophistication. It is often associated with royalty, wisdom, and stability.

The hex color #0A0A91, also known as Ultramarine, presents some accessibility challenges, especially when used as a text color on a white or light background. Its relatively low luminance contrast ratio makes it difficult for individuals with visual impairments to read text rendered in this color. To improve accessibility, it is recommended to pair Ultramarine with lighter colors such as white, light yellows, or pale blues for text. Alternatively, if Ultramarine is used as a background color, use lighter text colors such as white or light gray to provide sufficient contrast. Adhering to WCAG guidelines for contrast ratios is crucial to ensure readability and usability for all users, including those with disabilities. Providing sufficient contrast enhances the overall user experience and ensures that content is accessible to everyone, regardless of their visual abilities.
