General Information about Ultramarine

The hex color #2103B0, also known as Ultramarine, is a deep and vibrant shade of blue. It belongs to the blue color family and is often associated with feelings of calmness, trust, and authority. In the RGB color model, it is composed of 12.9% red, 1.2% green, and 69% blue. The color's prominence in art history is notable, as 'ultramarine' derives from the Latin 'ultramarinus,' meaning 'beyond the sea,' due to its original source being lapis lazuli imported from Asia. This color is widely used in various fields, including web design, graphic design, and fashion, to evoke a sense of sophistication and depth. Understanding its properties and associations can help designers and artists effectively utilize it in their creative endeavors.

The color #2103B0, a deep shade of ultramarine, presents certain accessibility challenges, especially when used as a foreground color against a white or light-colored background. Due to its low luminance, the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards, potentially making it difficult for users with visual impairments to read text or distinguish elements. To improve accessibility, consider pairing this color with a very light color such as white (#FFFFFF) or a light yellow (#FFFFE0), which significantly increases the contrast ratio, ensuring readability and usability for a wider audience. Alternatively, using #2103B0 for larger graphical elements or as a background color for light text can be effective. Avoid using it for crucial interactive elements without careful consideration of contrast.
