General Information about Ultramarine (#190DA6)

Ultramarine, represented by the hex code #190DA6, is a deep, saturated blue color. It is inspired by the natural pigment derived from lapis lazuli, a semi-precious stone, giving it a historical connection to artistry and luxury. In the RGB color model, #190DA6 consists of 9.8% red, 5.1% green, and 65.1% blue. This strong blue component is what gives Ultramarine its distinctive and intense hue. Ultramarine is often associated with qualities such as depth, stability, and confidence. It's a color that can evoke feelings of trust and authority, making it a popular choice in branding and visual communication. Due to its intensity, Ultramarine is best used as an accent color or in strategic design elements rather than as a primary background, as it can be visually overwhelming.

The color #190DA6, also known as Ultramarine, presents some accessibility challenges, particularly for users with visual impairments. Due to its dark hue and strong blue component, it may not provide sufficient contrast when used as text against a white or light-colored background. According to WCAG guidelines, sufficient contrast is essential for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #190DA6, it is crucial to ensure that the text size is large enough or to pair it with a very light color to meet these contrast requirements. Otherwise, users with low vision or color blindness may struggle to distinguish the text from the background. Using online contrast checkers can help to evaluate the color combination. Also, avoid using it for essential UI elements like interactive buttons or links without proper visual cues.
