General Information about Ultramarine

The hex color #110BA8, also known as Ultramarine, is a deep shade of blue. In the RGB color model, it consists of 6.67% red, 4.31% green, and 65.88% blue. Ultramarine is often associated with qualities such as depth, stability, and authority. It is a popular choice in branding for businesses that want to convey trust and professionalism. Historically, ultramarine pigment was derived from lapis lazuli, making it a highly prized color. In web design, it can be used to create a sense of sophistication, but care should be taken to ensure sufficient contrast for accessibility. The color falls under the blue color family and is a tertiary color.

The color #110BA8, a deep ultramarine, presents significant accessibility challenges. Its low luminance value of approximately 1% means it offers very little contrast against white backgrounds, failing WCAG's minimum contrast ratio requirements for text and interactive elements. For text to be legible and interactive elements to be discernible, it is crucial to pair this color with much lighter hues. White text on this background would be difficult to read for users with low vision or color blindness. To improve accessibility, consider using a lighter tint of ultramarine, or pairing it with a contrasting color that provides sufficient luminance difference, such as a bright yellow or a light grey. Tools like contrast checkers can help ensure compliance with accessibility standards.
