General Information about Ultramarine

The color #120a8f, commonly known as Ultramarine, is a deep, rich shade of blue situated towards the violet end of the spectrum. Its name originates from the Latin "ultramarinus," meaning "beyond the sea," as it was originally derived from the precious gemstone lapis lazuli, which was imported from distant lands. Historically, Ultramarine was highly valued as a pigment for paintings and artwork due to its exceptional brilliance and permanence. In color theory, Ultramarine is considered a cool color, evoking feelings of tranquility, depth, and sophistication. It is often associated with royalty, wisdom, and spirituality. In the RGB color model, #120a8f is composed of 7.06% red, 3.92% green, and 56.08% blue. In the CMYK color model, it consists of 87.49% cyan, 93.01% magenta, 0% yellow, and 43.92% black.

The hex color #120a8f, also known as Ultramarine, presents several accessibility considerations for web design. Its dark hue results in a low luminance value, requiring careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet AA compliance. When using #120a8f as a background, light colors like white or bright yellow are good choices for text to maximize readability. Conversely, avoid using dark or muted colors for text, as they may become illegible against the dark background. Also, consider providing alternative visual cues besides color alone to convey information, as individuals with color vision deficiencies may struggle to differentiate elements solely based on color. Implementing features like text labels or icons can enhance the overall accessibility of your design. Ensuring proper color contrast and providing redundant visual cues will make the content more inclusive for all users.
