General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0b019a, is a deep blue pigment originally derived from the mineral lapis lazuli. The name 'ultramarine' comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported to Europe from Asia. This color is known for its rich, intense hue and has been prized by artists for centuries. In modern times, synthetic ultramarine is widely available, offering the same vibrant color at a more affordable price. Ultramarine is commonly used in various applications, including paints, inks, plastics, and cosmetics, due to its stability and non-toxic properties. Its unique shade makes it a favorite choice for creating depth and atmosphere in artwork.

The hex color #0b019a, also known as Ultramarine, presents some accessibility challenges, especially in web design. Its dark hue results in low contrast when paired with similarly dark colors, making text and other elements difficult to read for users with visual impairments. To ensure inclusivity, it is crucial to use this color with light backgrounds, such as white or light yellow, to provide sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color as the sole indicator of important information, as colorblind users may not be able to distinguish it effectively. Supplement visual cues with text labels or icons to ensure universal accessibility.
