General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #210EA6, is a deep and vibrant shade of blue, reminiscent of the precious pigment derived from lapis lazuli. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported to Europe from mines in Asia. Chemically, it is a complex sodium aluminosilicate containing sulfur. In the RGB color model, #210EA6 consists of 12.9% red, 5.5% green, and 65.1% blue. It is widely used in art, design, and various industries for its intense and lasting color. Ultramarine offers a classic and timeless feel, often associated with royalty and sophistication.

The color #210EA6, also known as Ultramarine, presents some accessibility challenges, particularly when used as text on a white background. Its relatively low luminance contrast ratio can make it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine might fall short of these recommendations, necessitating careful consideration. To improve accessibility, consider pairing it with lighter background colors that offer sufficient contrast. Additionally, using Ultramarine for decorative elements or larger graphical components can mitigate accessibility concerns. Providing alternative color schemes that offer better contrast is also a good practice to ensure inclusivity for all users.
