It is often used to evoke a sense of trust and authority, making it a popular choice for corporate branding and designs.

Its intense and saturated nature makes it a favorite among artists and designers alike.

The hex color #181187, a deep ultramarine, presents accessibility challenges primarily due to its low luminance. When used as text on a white background, the contrast ratio is insufficient, making it difficult for individuals with visual impairments to read. To improve accessibility, consider pairing it with lighter colors, such as shades of white, cream, or light yellow, to ensure sufficient contrast. Additionally, providing alternative text descriptions for images or elements using this color is crucial. In terms of web design, it's advisable to avoid using this color for essential interactive elements unless accompanied by clear visual cues and sufficient contrast. Tools like contrast checkers can help determine if color combinations meet accessibility standards like WCAG (Web Content Accessibility Guidelines). Remember that ensuring accessibility is essential for inclusive design and reaching a wider audience.
