About Ultramarine

Ultramarine, represented by the hexadecimal color code #090A8E, is a deep and intense shade of blue, reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine pigment was highly prized and costly, making it a symbol of luxury and prestige, often associated with royalty and religious figures in art. In the RGB color model, it is composed of 3.53% red, 3.92% green, and 55.69% blue. This color evokes feelings of serenity, stability, and wisdom. In modern usage, Ultramarine is widely employed in graphic design, web development, and fashion to convey a sense of sophistication and depth. Its rich hue makes it a popular choice for creating visually striking and memorable designs, often used to suggest trust and authority.

The hex color #090A8E, also known as Ultramarine, presents significant accessibility challenges, primarily due to its extremely dark nature. When used as a background color, it necessitates very light text (ideally white or a very pale yellow) to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #090A8E, achieving these ratios can be difficult with many common text colors. Web developers must carefully test color combinations using contrast checkers to verify compliance. Moreover, avoid using this color for crucial interactive elements like buttons or links without thoroughly evaluating its impact on users with visual impairments. Using a lighter shade of blue or pairing it with a contrasting, lighter color can improve accessibility.
