General Information about #021AB2

The hexadecimal color code #021ab2, often referred to as International Klein Blue (IKB), represents a deep and intense shade of blue. This particular blue is highly saturated and possesses a unique vibrancy that sets it apart from other blues. IKB achieved fame through the French artist Yves Klein, who registered a patent for it in 1957. The color's impact in art and design stems from its ability to evoke a strong emotional response, often associated with feelings of depth, boundlessness, and the infinite. In the RGB color model, #021ab2 is composed of 0.78% red, 10.2% green, and 72.75% blue. This composition results in its distinct appearance, making it a powerful choice for designers seeking to create visually striking and memorable experiences.

The color #021ab2, a deep shade of blue also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its low luminance value necessitates careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. Given the darkness of #021ab2, pairing it with light colors like white (#ffffff) or very pale yellow is crucial to meet these standards. Using it for text on a dark background or with colors close in tone would render the content inaccessible. Furthermore, avoid using this color as the sole indicator for interactive elements; supplement it with text labels or icons for users who may not be able to distinguish the color effectively.
