About Ultramarine
Ultramarine, represented by the hexadecimal color code #100D8A, is a deep, vibrant shade of blue. It is reminiscent of the pigment derived from lapis lazuli, a semi-precious stone that was historically highly valued. In the RGB color model, Ultramarine is composed of 6.27% red, 5.1% green, and 54.12% blue. This high blue component contributes to its intense and saturated appearance. The color is often associated with concepts such as depth, stability, confidence, and authority. It is frequently used in branding and design to convey trust and reliability. Ultramarine is a popular choice for creating a sense of sophistication and elegance, especially when paired with complementary or contrasting colors.
The color #100d8a, also known as Ultramarine, presents accessibility challenges primarily due to its dark hue. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Tools like WebAIM's contrast checker can verify compliance. Moreover, avoid using this color for crucial interactive elements without careful consideration of focus indicators and hover states, ensuring these elements are clearly distinguishable. Users with low vision or color blindness may struggle to differentiate elements if the contrast is inadequate. Thoughtful design practices, including proper color pairings and alternative cues, can significantly improve the accessibility of content using this deep blue.

Web Design
In web design, Ultramarine can be used to create a sophisticated and professional look for websites related to technology, finance, or education. It can serve as a background color for headers or sidebars, or as a highlight color for key elements such as buttons and links. However, due to its darkness, it should be paired with light-colored text and ample white space to ensure readability and avoid overwhelming the user. Consider using it sparingly to draw attention to specific areas of the page and create a sense of depth and importance.
Interior Design
In interior design, Ultramarine can be used to create a bold and dramatic statement. It works well as an accent wall color in living rooms, bedrooms, or offices. It can also be used in furniture upholstery or decorative accessories such as pillows, curtains, and rugs. When using Ultramarine in interior design, it's essential to balance it with lighter colors and natural materials to prevent the space from feeling too dark or heavy. Consider pairing it with white, cream, gray, or wood tones to create a harmonious and inviting atmosphere.
Fashion
In fashion, Ultramarine can be incorporated into evening wear or formal outfits. It adds a touch of luxury and makes the outfit stand out, especially when combined with gold or silver accessories. This color can be utilized in dresses, suits, scarves, or even shoes, allowing for various expressions of style. Remember to balance it with neutral or lighter shades to prevent the overall look from becoming too overwhelming.
