General Information about Ultramarine

The hex color #1D04B0, also known as Ultramarine, is a deep shade of blue with a rich and intense character. Ultramarine is derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan by sea to Europe. This color is associated with royalty, wisdom, and spirituality, making it popular in art and design. In the RGB color model, #1D04B0 is composed of 11.4% red, 1.6% green, and 69% blue. Its high blue component gives it its characteristic depth and intensity. In the CMYK color model, it consists of 83% cyan, 98% magenta, 0% yellow, and 31% black. The color is versatile, lending itself to various applications.

The color #1D04B0, a deep ultramarine, presents some accessibility challenges, particularly when used as a background for text. Its low luminance can create insufficient contrast with lighter text colors, making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. Using a very light color such as white or a pale yellow can somewhat mitigate this. However, careful consideration is still required. When using this color as a primary UI element, ensure sufficient contrast with interactive elements like buttons and links to ensure they are easily identifiable. Adding a darker shade as the text will also not be a solution. The color should be used with care.
