About Hex Color #0B0AAA

The hexadecimal color code #0B0AAA represents a specific point in the color space, defining a unique hue of blue often referred to as ultramarine. It is composed of 0B (11 in decimal) parts red, 0A (10 in decimal) parts green, and AAA (170 in decimal) parts blue. In the RGB (Red, Green, Blue) color model, this translates to relatively low amounts of red and green, with a high proportion of blue, resulting in a deep, saturated blue hue. Hexadecimal color codes are commonly used in web design and digital graphics to precisely specify colors. This is due to the fact that the color is easily used in CSS styling, and other design languages. Its usage should be based on accessibility standards to ensure readability for all users.

The color #0B0AAA, a deep shade of ultramarine, presents specific accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio may fall below the WCAG (Web Content Accessibility Guidelines) minimum threshold of 4.5:1 for normal-sized text. This can make it difficult for users with visual impairments to read the content comfortably. To improve accessibility, consider pairing #0B0AAA with lighter background colors like white (#FFFFFF) or very pale yellows (#FFFFE0). Conversely, if #0B0AAA is used as a background, opt for text colors that offer high contrast, such as white (#FFFFFF) or light gray (#D3D3D3). Tools like contrast checkers can precisely assess the contrast ratio and provide recommendations for adjustments. Ensuring sufficient contrast enhances readability for all users, including those with low vision or color blindness.
