The color #170B8D, a deep ultramarine, presents some accessibility challenges, primarily due to its low luminance value. When used as a background color, it necessitates very light text for sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color might not be suitable for extensive reading or situations where visual clarity is paramount, especially for users with visual impairments. Careful consideration should be given to text size, font weight, and spacing to enhance readability. Using a color contrast checker can help ensure compliance with accessibility standards and provide a better user experience. Avoid pairing it with other dark colors. Lighter shades of grey, yellow or white usually work well.

Applications
Web Design Accent
In web design, Ultramarine can be used as a strong accent color for buttons or headings to draw attention. Its depth conveys trust and stability, making it suitable for financial or governmental websites. However, due to its low luminosity, it is essential to use it sparingly and pair it with light text and backgrounds to maintain readability and accessibility. Consider using it as a secondary color in a palette where a lighter tint of blue or white serves as the primary background.
Interior Design Accent
In interior design, Ultramarine can add a touch of sophistication and depth to a room. It works well as an accent wall color in living rooms or bedrooms, creating a calming and serene atmosphere. It can also be used in decorative elements such as cushions, curtains, or artwork. Pair it with neutral colors like white, gray, or beige to balance the intensity. Metallic accents like gold or silver can also enhance the luxurious feel of Ultramarine.
Fashion Accent
In fashion, Ultramarine can be used in formal wear or as accents in casual wear. For example, a scarf, tie, or handbag in ultramarine. For formal wear such as an evening gown or suit, this color is best suited to be paired with black, silver, or gold accessories to complement the depth and richness of the blue. The color also works well in combination with denim.
