General Information about Ultramarine

The color #001090, commonly known as Ultramarine, is a deep and rich shade of blue that falls within the range of cobalt blues. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from lapis lazuli imported from Asia. Ultramarine is characterized by its intense, slightly reddish blue hue, and it has been highly valued throughout history, particularly in art, for its brilliance and permanence. In the RGB color model, #001090 is composed of 0% red, 6.3% green, and 56.3% blue. It is often associated with depth, stability, and wisdom, making it a popular choice for brands seeking to convey trustworthiness and authority. However, due to its darkness, it is important to use it carefully in design to ensure readability and accessibility.

The hex color #001090, a deep shade of ultramarine, presents significant accessibility challenges, especially in text applications. Its very low luminance value of 0.005 necessitates careful consideration of color contrast to ensure readability for users, including those with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. Therefore, when using #001090 for text, it's crucial to pair it with a very light color to meet these contrast requirements. White (#FFFFFF) or light yellow (#FFFF00) would be suitable choices. Furthermore, avoid using this color for crucial UI elements like buttons or links without sufficient contrast, as it can hinder usability. Remember to test the color combination with accessibility tools to verify compliance with accessibility standards and provide an inclusive user experience.
