Ultramarine
General Information about #100CA8
The hex color #100CA8, also known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and exhibits a strong presence with its rich pigmentation. In the RGB color model, it is composed of 6.27% red, 4.71% green, and 65.88% blue. This combination gives it a distinctive and powerful visual characteristic. Ultramarine blue has a history steeped in art and culture, traditionally derived from the mineral lapis lazuli. Its synthetic version is now widely used in various industries, ranging from paints and pigments to plastics and cosmetics. Its evocative nature makes it a popular choice for designs aiming to convey trust, stability, and depth.
The color #100CA8, a deep ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 4% means that it offers very little contrast against dark backgrounds, rendering it nearly invisible. To ensure readability and usability for individuals with visual impairments, it is imperative to use #100CA8 only against very light backgrounds. A high contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as stipulated by WCAG guidelines. When employing this color, consider using tools to verify color contrast ratios to prevent potential accessibility barriers. Furthermore, avoid using #100CA8 as the sole indicator of important information, such as links or error messages, as colorblind users may not be able to distinguish it. Supplement color with other visual cues like icons, underlines, or bold text.

Applications
Web Design
In web design, #100CA8 can be used for creating a sophisticated and trustworthy aesthetic. It is best suited for backgrounds of call-to-action buttons or as an accent color for highlighting important elements. However, it should be paired carefully with lighter text colors like white or off-white to ensure readability. For instance, a website for a financial institution might use #100CA8 in its navigation bar to convey stability and security. Its use in interactive elements should be judicious to avoid overwhelming the user, and should always prioritize accessibility by maintaining sufficient contrast with foreground elements.
Fashion
In fashion, #100CA8, or Ultramarine, can be incorporated into designs to evoke a sense of elegance and depth. It can be used as a solid color for statement pieces like dresses or coats, or as an accent color in accessories such as scarves or handbags. This deep blue pairs well with neutral tones like gray, beige, and white, as well as metallic accents like gold or silver. For evening wear, #100CA8 provides a sophisticated alternative to black, offering a rich and luxurious appeal. When designing with this color, consider the texture of the fabric to enhance its visual impact.
Interior Design
In interior design, #100CA8 brings a sense of depth and calmness to spaces. It can be used as an accent wall color in living rooms or bedrooms to create a focal point, or incorporated through furniture pieces like sofas or armchairs. This deep blue works well in rooms with ample natural light, as it can make smaller spaces feel darker. Complementary colors like gold, yellow, and white can be used to balance the intensity of #100CA8 and create a harmonious environment. Accessories such as cushions, curtains, and rugs in lighter shades can soften the overall look.
