Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hexadecimal color code #170A91, is a deep, rich blue hue reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine was highly prized for its vibrancy and permanence, making it a favorite among artists for centuries. The name itself, "ultramarine," means "beyond the sea," reflecting its origin as a pigment imported from distant lands. In the realm of color theory, ultramarine is classified as a cool color, evoking feelings of calmness, stability, and depth. Its intense saturation makes it a powerful choice for adding visual interest and drama to designs. However, its darkness requires careful consideration of contrast to ensure readability and accessibility.
The hex color #170A91, a deep ultramarine, presents significant accessibility challenges. Its low luminance of 3.3 cd/m² results in poor contrast against white backgrounds, failing WCAG AA and AAA standards for normal text. To ensure readability, it's crucial to use it with very light colors, ideally whites or near-whites. Large text has more leeway, but careful evaluation is still necessary. Consider using a color contrast checker to verify compliance. For users with visual impairments, the lack of contrast can make text and interface elements disappear. Providing sufficient contrast is essential for an inclusive design. Furthermore, avoid using this color as the sole indicator for important information, such as form validation errors, as colorblind users may not perceive it.

Applications
Web Design Accent
Ultramarine (#170A91) can be used sparingly in web design as an accent color to highlight key elements like buttons or links. Due to its dark nature and low contrast, it's not suitable for large blocks of text or backgrounds. It pairs well with lighter, neutral colors such as whites, creams, or light grays. In user interfaces, consider using it for icons or small graphical elements where its richness can add depth without compromising readability. Careful attention to color contrast is essential to maintain accessibility standards, ensuring that all users can easily interact with the design.
Interior Design Accent
In interior design, ultramarine can be incorporated as a bold statement color in accent walls, decorative accessories, or upholstery. Its depth and richness create a luxurious and sophisticated atmosphere. To balance the intensity, pair it with lighter, neutral tones such as whites, beiges, or grays. Metallic accents like gold or silver can enhance its opulent feel. Consider using it in rooms with ample natural light to prevent the space from feeling too dark. As an alternative, smaller doses in artwork or decorative pillows can add a pop of color without overwhelming the space.
Fashion Accent
In fashion, Ultramarine can be used as a primary color for evening wear or special occasion outfits. It's a color that exudes confidence and sophistication. Accessorize with gold or silver jewelry to enhance its luxurious feel. For more casual wear, consider using it as an accent color in scarves, handbags, or shoes. Pair it with neutral colors such as black, white, or gray to create a balanced and stylish look. Avoid using it as the main color for everyday wear, as it can be quite overpowering. Use it sparingly to make a statement and add a touch of elegance to your wardrobe.
