General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0811A6, is a deep, intense blue hue often associated with qualities like wisdom, trust, and stability. It falls within the blue color family and is characterized by its relatively low brightness and high saturation. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it a highly valued pigment in art and decoration. In color theory, Ultramarine is considered a cool color, often used to convey a sense of calmness and serenity. It can be effectively employed in various design contexts, from web design and branding to interior decor and fashion, to evoke feelings of reliability and professionalism. However, due to its darkness, it's important to use it carefully and in conjunction with lighter colors to ensure legibility and visual balance.

The color #0811A6, Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low lightness value (approximately 3%) means that text or other elements rendered in this color require very high contrast against a light background to be legible. According to WCAG guidelines, to achieve AA compliance, text using this color needs to be at least 4.5:1 contrast ratio against its background, while AAA compliance requires a 7:1 ratio. Due to its dark nature, using #0811A6 for crucial visual elements should be avoided unless paired with a very light color like white or a pale yellow to ensure readability. Proper color contrast analysis tools should be used to validate compliance. Additionally, consider providing alternative styling options to users who may have difficulty perceiving the color due to color blindness or other visual impairments. The dark hue may be difficult to differentiate from black, exacerbating usability problems.
