It's characterized by its intense saturation and near-absence of green, giving it a distinctive ultramarine appearance. In the RGB color model, #0022aa is composed of 0% red, 13.3% green, and 66.7% blue. This specific combination creates a color that is both striking and evocative, often associated with depth, stability, and creativity. It finds use in art, design, and various other applications where a strong, impactful blue is desired.

The hex color #0022aa, a deep shade of blue, presents some accessibility challenges, particularly when used as a background or text color. Its low luminance value means it has a low contrast ratio against standard white backgrounds. This can make text difficult to read, especially for users with visual impairments such as low vision or color blindness. To ensure accessibility, it's crucial to pair #0022aa with a light color that provides sufficient contrast, ideally adhering to WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Tools are available online to check color contrast ratios. When using this color for interactive elements like buttons, ensure the contrast is maintained in hover and focus states as well.
