General Information about Ultramarine

Ultramarine, represented by the hex code #0F188C, is a deep blue color with a rich history. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from lapis lazuli imported from Asia. This color is often associated with royalty, intellect, and the ocean depths. In color psychology, Ultramarine can evoke feelings of calmness, trust, and stability. It is a strong and sophisticated color, often used to convey authority and professionalism. It should be used strategically, as it can also create a sense of distance if overused. Its dark tone means it pairs well with lighter colors to achieve balance and readability.

The color #0F188C, also known as Ultramarine, presents several accessibility considerations for web development. Due to its dark hue, it's crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Using a light color like white or a pale yellow for text on an Ultramarine background will typically provide adequate contrast. However, tools like contrast checkers should be employed to verify compliance. Avoid pairing this color with other dark shades, as it may render content illegible for users with visual impairments. Also, consider users with color blindness by providing alternative cues beyond color alone.
