General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #040D94, is a deep, rich shade of blue. It closely resembles the pigment derived from the mineral lapis lazuli, which has been prized since antiquity for its intense color. In the RGB color model, #040D94 consists of 1.57% red, 5.1% green, and 58.04% blue. This composition explains its strong blue character. In the CMYK color model, it's composed of 97% cyan, 91% magenta, 0% yellow, and 42% black. This color is often associated with qualities such as depth, stability, and authority, making it a popular choice for branding and visual communication where these attributes are desired. Ultramarine is a non-spectral color because it is not found on the visible spectrum, but is rather a mixture of other colors.

The color #040D94, also known as Ultramarine, presents significant accessibility challenges, particularly when used for text or interactive elements. Its extremely low lightness value (close to black) means that it requires very light or white text to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. Using #040D94 as a background color with dark text would fail these requirements, making the content difficult or impossible for users with visual impairments to perceive. When using this color, careful consideration must be given to the foreground color to ensure accessibility. Tools like contrast checkers should be employed during the design process.
