General Information about Ultramarine

The hex color #0B0BA9, known as Ultramarine, is a deep, rich shade of blue. It is composed of 4.3% red, 4.3% green, and 66.3% blue. In the RGB color space, it is a vibrant and intense color, commonly associated with depth, stability, and sophistication. Ultramarine derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally made from lapis lazuli imported from Asia. Historically, it was highly prized as a pigment for paints and dyes. Today, it is widely used in digital design, fine arts, and various other applications. Its hex code representation makes it easily adaptable for web and graphic design, allowing for consistent color representation across different media. The color exudes a sense of trust and confidence.

The color #0B0BA9, also known as Ultramarine, presents some accessibility challenges, particularly when used for text or interactive elements. Its dark hue means that it requires a very light foreground color to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Ultramarine, careful consideration must be given to the choice of foreground color to meet these contrast requirements. Using online contrast checkers is advisable to verify compliance. Additionally, avoid using Ultramarine as the sole indicator for interactive elements; provide supplementary cues like underlines or icons to aid users with visual impairments or color blindness. Ensuring adequate spacing and sizing of elements is also crucial for improving usability.
