General Information about Ultramarine

Ultramarine, represented by the hex code #121289, is a deep blue color known for its rich and intense hue. It is a color that evokes feelings of calmness, sophistication, and depth. Historically, Ultramarine was derived from the mineral lapis lazuli, making it a highly valued pigment in art. The name 'Ultramarine' literally means 'beyond the sea,' reflecting its origin from overseas sources. In the RGB color model, #121289 is composed of 7.1% red, 7.1% green, and 53.7% blue. This high blue component is what gives Ultramarine its distinctive and vibrant appearance. The color is often associated with royalty, spirituality, and knowledge, making it a popular choice in various design applications. Its unique and captivating presence adds a touch of elegance and intrigue to any visual composition, making it a versatile and timeless color choice.

The color #121289, also known as Ultramarine, presents significant accessibility challenges, especially when used as a background or text color. Its dark hue results in a low luminance value, making it difficult to achieve sufficient contrast with lighter foreground elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text to ensure readability for users with visual impairments. When using #121289 for text, it's crucial to pair it with a very light color such as #FFFFFF (white) to meet these contrast requirements. For backgrounds, lighter shades of gray or pastel colors might work better. Web developers should use tools to check color contrast ratios to make sure their designs are accessible to all users, including those with low vision or color blindness. Consideration should also be given to users who may be viewing the content on different screens or under different lighting conditions, as these factors can impact perceived contrast.
