General Information about #0103e5

#0103e5 is a hexadecimal color code representing a deep shade of blue. In the RGB color model, it consists of 0.4% red, 1.2% green, and 89.8% blue. This significant dominance of blue gives the color its characteristic appearance. In the CMYK color model, used for printing, it comprises 99.5% cyan, 98.7% magenta, 0% yellow, and 10.2% black. This color is rarely found in nature in its pure form, making it often associated with artificial or digitally created environments. It is commonly used to represent technology, innovation, and futuristic themes. The color's high saturation and low luminance make it visually striking but also challenging to use effectively in design, particularly regarding accessibility.

The hex color #0103e5, a deep, vibrant blue, presents significant accessibility challenges, particularly in web design. Its extremely low luminance value of 0.006 makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) success criteria. Foreground text using #0103e5 requires very light backgrounds to meet the minimum contrast ratio of 4.5:1 for Level AA compliance, crucial for users with moderate visual impairments. For Level AAA compliance, demanding a 7:1 ratio, it's even more restrictive. When using this color for interactive elements like buttons or links, consider providing additional visual cues besides color alone, such as underlines, borders, or icons, to ensure usability for users with color vision deficiencies. Thoroughly test color combinations with accessibility evaluation tools to confirm compliance and optimal readability.
