General Information about Ultramarine (#0B108D)

#0B108D, commonly referred to as Ultramarine, is a deep and rich shade of blue within the blue color family. This hex code represents a specific point in the color spectrum, characterized by its strong blue undertones and a relatively low saturation. Ultramarine historically derives its name from the pigment originally made from lapis lazuli, a rare and expensive stone imported from overseas ('ultra marinus' in Latin). The color is often associated with depth, stability, and sophistication. In digital contexts, #0B108D is used to define the color of various elements, from website backgrounds to graphic design components. Its perceived darkness means that careful consideration should be given to the contrast it provides with other colors, especially text, to maintain legibility and accessibility.

The hex color #0B108D, also known as Ultramarine, presents several accessibility challenges, particularly in web design. Its dark hue results in low contrast when paired with lighter text colors like white or yellow, which is critical for readability. Insufficient contrast can hinder users with visual impairments, such as those with low vision or color blindness, from easily distinguishing text or interface elements. To ensure accessibility, it's crucial to use a color contrast checker to verify that the color combination meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider using lighter shades of blues or yellows as foreground colors to enhance visibility and overall user experience.
