#0B1DDB

General Information about #0B1DDB

The hexadecimal color code #0B1DDB represents a specific shade of dark blue. It is composed of 0B (11 in decimal) red, 1D (29 in decimal) green, and DB (219 in decimal) blue. In the RGB (Red, Green, Blue) color model, this translates to a relatively low red and green component with a high blue component, resulting in a predominantly blue color. Hex codes are commonly used in web design and digital graphics because they provide a precise way to specify colors across different platforms and devices. Understanding the composition of a hex code allows designers and developers to accurately reproduce and manipulate colors for various applications, ensuring consistency and visual appeal. The color can be adjusted by modifying the different components of RGB.

The color #0B1DDB, a dark blue, presents significant accessibility challenges, especially when used as text against a white or light-colored background. The contrast ratio is very low, failing to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Users with visual impairments, including those with low vision or color blindness, may find it extremely difficult or impossible to distinguish the text from the background. To improve accessibility, it is crucial to use this dark blue with a much lighter foreground color, such as a light yellow (#FFFF00) or white (#FFFFFF), to ensure sufficient contrast. Alternatively, if #0B1DDB is used as a background, a very light text color should be used. Careful consideration should be given to the font size and weight as well, as larger and bolder fonts can improve readability at lower contrast levels. Tools like contrast checkers are invaluable for verifying that the color combinations meet accessibility standards.
