General Information about #110B82

The hexadecimal color code #110B82 represents a deep shade of blue, often referred to as Ultramarine. It is created by combining relatively low amounts of red (17) and green (11) with a significantly larger amount of blue (130) in the RGB color model. In the CMYK color model, which is often used for printing, #110B82 translates to approximately 87% cyan, 92% magenta, 0% yellow, and 49% black. Ultramarine blue has a long and rich history, originally derived from the rare and expensive mineral lapis lazuli. Due to its association with royalty and religious figures, it was highly valued in the art world. Today, synthetic pigments allow for much wider availability and use. The color conveys feelings of trust, intelligence, and loyalty. Therefore, it is often used in designs for businesses and organizations that want to project a sense of authority and credibility.

The color #110B82, a deep ultramarine, presents some accessibility challenges, particularly in text-based contexts. When used as text against a white or very light background, the contrast ratio is likely to be insufficient, 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 (14pt bold or 18pt regular). Therefore, careful consideration must be given to the background color it is paired with. To improve accessibility, it is recommended to use #110B82 with lighter shades of yellow, orange, or even very light blues to achieve sufficient contrast. Tools like WebAIM's contrast checker can be invaluable in determining whether a particular color combination meets accessibility standards. Additionally, avoid using this color for crucial interactive elements or informational graphics without proper contrast, as it can exclude a significant portion of your audience. Ensuring sufficient contrast is not just about meeting legal requirements; it is about creating an inclusive experience for all users.
