General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F1889, is a deep, rich shade of blue. It is a tertiary color, created by mixing primary and secondary colors. Ultramarine derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported from overseas, particularly from lapis lazuli, a semi-precious stone. Lapis lazuli was ground into pigment and used extensively by Renaissance painters. The color is known for its exceptional depth and vibrancy. In modern usage, Ultramarine conveys feelings of stability, trust, and intelligence. It is often associated with corporate identities, academic institutions, and governmental organizations due to its professional and reliable connotations.

The accessibility of #0F1889 (Ultramarine) should be carefully considered in web design. Its deep, saturated hue can pose challenges for users with visual impairments. When used as text, ensure a high contrast ratio against the background; ideally, aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as defined by WCAG guidelines. White or very light shades of yellow or green often work well as foreground colors against Ultramarine. Avoid pairing it with similar dark colors, as this reduces readability. When used for interactive elements like buttons or links, provide additional cues such as underlines or icons to ensure usability. Also consider that color perception varies; testing with users who have different types of color vision deficiencies is crucial to ensure the design is accessible to everyone.
