General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #121690, is a deep and rich shade of blue. It originates from the pigment derived from the gemstone lapis lazuli, highly valued since ancient times. Its name literally means "beyond the sea", referring to its import from Asia to Europe. In the RGB (Red, Green, Blue) color model, #121690 consists of 7.06% red, 8.63% green, and 56.47% blue. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it is composed of 87% cyan, 85% magenta, 0% yellow, and 44% black. This color is often associated with royalty, intelligence, and stability. Ultramarine is used in various applications, ranging from fine art and fashion to web design and branding, because of its depth and elegance.

The color #121690, also known as Ultramarine, presents significant accessibility challenges due to its dark nature and low contrast against light backgrounds. For web content, using this color as text on a white or very light background would fail WCAG (Web Content Accessibility Guidelines) standards for color contrast. To improve accessibility, it is essential to pair it with much lighter text colors, such as white or very light yellows, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, using #121690 as a background color requires similarly light text to meet accessibility standards. Employing tools to check color contrast ratios during design is crucial. Also, consider users with color vision deficiencies; relying solely on color to convey information can exclude these users. Supplementing color with text labels or other visual cues ensures inclusivity.
