The color #1A0E8B, also known as Ultramarine, is a deep, saturated blue hue that evokes feelings of sophistication, depth, and creativity. It belongs to the blue color family and is often associated with the sea and sky, conveying a sense of calm and tranquility. In the RGB color model, it is composed of 10.2% red, 5.5% green, and 54.5% blue. Ultramarine has a rich history, originally derived from the precious gemstone lapis lazuli, making it a highly valued pigment in art.

It's a versatile color, and its depth makes it an excellent choice for creating contrast and visual interest.

The hex color #1A0E8B, also known as Ultramarine, presents accessibility challenges due to its dark hue. When used as a background color, it requires very light text (ideally white or a very pale yellow) 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 AA compliance. Using #1A0E8B with text colors that are not sufficiently light can result in poor readability, especially for users with visual impairments. Therefore, careful consideration of color contrast is essential when incorporating this color into web design to ensure an inclusive and accessible experience for all users. Tools like contrast checkers can help verify compliance with accessibility standards.
