Today, synthetic versions make it more accessible, yet it retains its association with luxury and sophistication. Its deep hue evokes feelings of depth, stability, and calmness.
The color #2308AC, Ultramarine, presents some accessibility challenges due to its dark hue. When used as a background color, it requires light-colored text (white or a very pale shade) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. Ultramarine's darkness means careful selection of text colors is crucial. For users with visual impairments, providing sufficient contrast is vital. Additionally, avoid using Ultramarine to convey information alone; supplement it with text or icons. When used for interactive elements like buttons, ensure that hover and focus states provide clear visual differentiation to aid users who rely on keyboard navigation or screen readers.

Applications
Web Design Accent
In web design, Ultramarine can serve as a powerful accent color for headings, buttons, or navigation elements. Its depth can create a sense of sophistication and trust. However, due to accessibility considerations, it's best used sparingly or paired with high-contrast text. For example, a website for a financial institution might use Ultramarine to convey stability, while a tech company could use it to suggest innovation. It also works well in dark mode themes as a background or highlight color, provided the foreground elements are appropriately light.
Fashion Design
In fashion, Ultramarine can be used to create bold and elegant looks. A dress in this color can be striking, while accessories like scarves or handbags can add a touch of sophistication to an outfit. Because of its richness, it pairs well with neutral colors like beige, gray, or black. It can also be combined with contrasting colors like yellow or orange for a more vibrant and playful effect. This color can be used in both casual and formal settings, depending on the fabric and style.
Interior Design Accent
Ultramarine, with its rich and saturated color, adds a touch of sophistication and depth to any interior space. It can be used as an accent color on a single wall, adding a dramatic focal point to a room. When paired with neutral tones like cream, gray, or white, it creates a balanced and harmonious atmosphere. The color also works well in rooms with natural light, as the sunlight enhances its vibrancy, making it ideal for bedrooms, living rooms, or even home offices where a sense of calm and focus is desired.
