About Ultramarine (#0A148E)
The hex color code #0A148E represents a deep shade of ultramarine blue. In the RGB color model, it consists of 3.92% red, 7.84% green, and 55.69% blue. This indicates a strong bias towards the blue primary color, resulting in its characteristic deep blue appearance. Ultramarine, historically derived from the precious gemstone lapis lazuli, has been prized for its rich, vibrant hue. In the digital realm, #0A148E can be used in various applications such as web design, graphic design, and digital art to convey feelings of trust, stability, and depth. Due to its darkness, it is crucial to consider contrast ratios when using this color with text or other visual elements to ensure readability and accessibility.
The color #0A148E, a deep ultramarine, presents several accessibility considerations for web development. Due to its low lightness value, it's crucial to ensure sufficient contrast when used as a background or foreground color. 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. This deep blue may require light-colored text (white or light gray) to meet these standards. Tools like contrast checkers can help verify compliance. Also, avoid using this color as the sole indicator of interactive elements such as links or buttons; supplement it with other visual cues like underlines or icons to ensure usability for users with color vision deficiencies. When using this color, consider users with cognitive disabilities; simple layouts and clear typography enhance readability.

Web Design
In web design, ultramarine (#0A148E) can be used to create a sophisticated and professional look for websites in the finance, technology, or education sectors. It can serve as a background color for headers or footers, paired with white or light gray text for optimal readability. Buttons and interactive elements can adopt this color with a lighter hover state to indicate interactivity. However, overuse of this dark shade can make a website appear heavy, so it is best used sparingly as an accent color.

The deep hue can be grounded by using natural materials like wood or stone, and pops of brighter colors like gold or coral can create visual interest.
Fashion
In fashion, ultramarine can be used for elegant evening wear or as a bold accent color in accessories. It can be used as silk scarfs, dresses, or bags. This color is best used in formal occasions.
