General Information about Ultramarine

Ultramarine, represented by the hex code #0B13A9, is a deep blue color known for its rich and intense hue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it a pigment highly valued by artists. The name 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' referring to the pigment's origin from lands beyond the sea. Today, synthetic ultramarine is widely available, retaining the same vibrant color at a more accessible cost. This color is often associated with royalty, intellect, and stability, and is used to evoke feelings of trust and authority. In color psychology, deep blues like ultramarine are believed to promote a sense of calm and serenity.

The contrast ratio of #0B13A9 (Ultramarine) with white text is quite low, making it difficult for users with visual impairments to read. A higher contrast ratio is essential for ensuring readability and accessibility, especially for users with low vision or color blindness. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using a lighter text color, such as white or a very pale yellow, against the Ultramarine background, or use a darker background color with white text. You should test the color combination with accessibility evaluation tools to verify that it meets accessibility standards. Another strategy is to increase the font size or weight, which can improve readability even with a lower contrast ratio. Also, ensure other visual cues are available to convey information, especially if color is used to differentiate elements.
