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.

Applications
Web Development
In web development, #0103e5 can be used sparingly for accent colors or branding elements, especially in designs aiming for a futuristic or tech-oriented feel. It can be applied to highlight interactive elements, but with careful consideration of contrast ratios. As a primary background color, it presents significant accessibility challenges due to its low luminance. It's better suited for smaller UI components or decorative accents. Its vibrant nature also makes it suitable for data visualization, where distinct colors are needed to differentiate between data sets.
Fashion & Beauty
In fashion and beauty, #0103e5 can be used to create bold and striking looks. It is often used in eye shadow palettes, eyeliner, and nail polish to add a pop of color. In clothing, it can be used in small doses as an accent color or as a statement piece. For example, a bright blue scarf or handbag can add a touch of personality to an outfit. When using #0103e5 in fashion, it is important to consider the overall color palette and the wearer's skin tone.
Interior Design
In interior design, the deep blue color #0103e5 is applicable to accent walls, decor pieces or light effects to add vibrancy. Given the strong nature of the color, it can serve as a dynamic element in rooms that leverage light to create atmosphere, such as through diffused lighting or ambient LED strips embedded in interior architecture. When paired correctly with neutrals, the color can bring life to minimalist design, while also allowing other elements of the room, such as texture-rich fabrics or artisanal crafts, to stand out.
