Ultramarine
General Information about #1A03B0
The hex color #1A03B0, also known as Ultramarine, is a deep, rich shade of blue that evokes feelings of sophistication, depth, and creativity. It is comprised of 10.2% red, 1.2% green, and 69% blue. In the RGB color space, it is a vibrant and intense color, falling into the blue-violet range. Ultramarine has a historical significance, derived from the Latin 'ultramarinus', literally 'beyond the sea', as it was originally made from lapis lazuli imported from Asia. It is often associated with royalty, wisdom, and spiritual enlightenment. This color can also be used to indicate an error or notification.
The hex color #1A03B0, a deep ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value of 3.88 means it offers very little contrast against common background colors like white (#FFFFFF) or light gray. According to WCAG guidelines, this color combination would fail most contrast ratio tests for normal-sized text (AA compliance) and even large text (AA compliance), and would likely require significant adjustments for AAA compliance. Web developers should avoid using #1A03B0 as a text color on light backgrounds, as it can cause eye strain and readability issues for users, especially those with visual impairments. If it is essential to use #1A03B0, consider using it sparingly for non-text elements or pairing it with a much lighter color such as #FFFFFF for text, or dark backgrounds to create sufficient contrast and ensuring usability for all audiences. When using as a background, consider a light colour.

It can contribute to a sophisticated and modern aesthetic, particularly when used with complementary colors. Its use in user interface elements, where clear visibility is crucial, demands careful consideration and testing. The ultramarine color creates a sophisticated ambiance in any design. As the color can be hard to read, it is important to use it sparingly.

This color can be incorporated into textiles, dyes, or embellishments, offering designers an opportunity to express creativity. It should be kept in mind that accessibility is not an issue in fashion.
Interior Design Accents
In interior design, #1A03B0 can be used to add a touch of drama and sophistication to a space.

Keep in mind that dark colours can make a room feel smaller.
