General Information about #1B15D1

The hexadecimal color code #1B15D1 represents a dark shade of blue. It is composed of 10.6% red, 8.24% green, and 82% blue. In the RGB color model, this color is created by mixing these three primary colors at these specific percentages. The color is mostly blue, giving it a strong blue appearance. This color has a wavelength of approximately 466.46 nm. In web design, hexadecimal color codes are commonly used to specify colors for various elements, ensuring consistency across different browsers and devices. Understanding the composition of hexadecimal colors allows designers and developers to create visually appealing and harmonious color schemes. The dark nature of this particular shade of blue suggests it would be best suited for backgrounds or accent elements, rather than for primary text.

The hex color #1B15D1 presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against white backgrounds, making text and interface elements difficult to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text according to WCAG guidelines. This color likely falls short of these recommendations. To improve accessibility, consider using lighter shades of blue or pairing it with a very light color, such as white or light yellow, to increase contrast. Additionally, avoid using this color for critical information or interactive elements without sufficient contrast, and provide alternative cues, such as icons or text labels, to enhance usability for all users.
