#0A09CD

General Information about #0A09CD

The hex color #0A09CD, often described as a dark shade of blue, is a specific point in the color spectrum within the RGB (Red, Green, Blue) color model. In this model, colors are defined by the intensity of red, green, and blue light. #0A09CD translates to 10 parts red, 9 parts green, and 205 parts blue. This strong presence of blue light gives the color its dominant blue appearance. The color's darkness comes from the relatively low values of red and green, and from the blue being less than maximum. Hexadecimal color codes are commonly used in web design and digital graphics to precisely define colors for display on screens. This color evokes feelings of trust and loyalty, and is often associated with technology, knowledge, and professionalism. However, its darkness can also be seen as serious or somber.

The hex color #0A09CD, a deep shade of dark blue, presents significant accessibility challenges, especially in web design. Its low luminance value means that text rendered in this color against a white or light background will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. This can make content difficult to read for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, consider using #0A09CD sparingly for purely decorative elements. When using it for text or interactive elements, pair it with very light colors like white (#FFFFFF) or very bright colors like yellow (#FFFF00) to meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Alternatively, consider using a lighter tint of blue, or a different color altogether, to improve readability while maintaining the desired aesthetic. Proper accessibility considerations make your designs inclusive and user-friendly for everyone.
