Dark Blue

General Information

The hexadecimal color code #0F00CA represents a dark shade of blue. It is composed of 5.9% red, 0% green, and 79.2% blue. In the RGB color model, this corresponds to the numerical values of 15, 0, and 202, respectively. Hex color codes are commonly used in web design and digital graphics to specify colors accurately. The color #0F00CA would be perceived as a cool, deep blue, often associated with tranquility, depth, and professionalism. Its high blue component makes it suitable for creating a sense of calmness and stability in designs. However, due to its low lightness, careful consideration should be given to its contrast with other colors, particularly when used for text or interface elements, to ensure accessibility and readability.

The hex color #0F00CA, a dark blue hue, presents significant accessibility challenges, especially when used as text or interactive elements against a white or light-colored background. Its low luminance value (approximately 3% of the maximum possible luminance) means that the contrast ratio against white will likely fall far short of the WCAG guidelines' minimum requirement of 4.5:1 for normal text and 3:1 for large text. Consequently, users with low vision or color vision deficiencies may struggle to distinguish text or interface elements using this color. When using #0F00CA, web developers should prioritize careful pairing with very light colors to ensure sufficient contrast. Alternative strategies include using a lighter shade of blue, adding a text shadow, or using a different color altogether. Providing adequate color contrast is essential for inclusive design and ensuring a positive user experience for all.

However, it should be used sparingly to avoid overwhelming the user interface, as its dark nature can reduce readability if overused.
