General Information about Ultramarine

The hex color #0C0494, also known as Ultramarine, is a deep, rich shade of blue. It resides within the blue color family and is characterized by its strong saturation and relatively low luminance. In the RGB color model, it is composed of 4.71% red, 1.57% green, and 58.04% blue. In the CMYK color model, which is used for printing, it consists of 92% cyan, 97% magenta, 0% yellow, and 42% black. Ultramarine's historical significance stems from its origin as a pigment derived from the precious stone lapis lazuli, making it highly valued in art and decoration. Its name literally means 'beyond the sea', reflecting its importation to Europe from mines in Asia.

The hex color #0C0494, a deep ultramarine, presents accessibility challenges, especially in text-based contexts. Its low luminance value of 2 means it offers insufficient contrast against similarly dark backgrounds, making content illegible for users, particularly those with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color falls significantly short, necessitating careful consideration of foreground colors. Light shades of yellow, white, or other high luminance colors are crucial to ensure readability. When using #0C0494 for interactive elements, ensure sufficient visual cues beyond color alone are present to meet WCAG 2.1 success criteria.
