About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957. What sets IKB apart is its unique vibrancy and intensity, achieved by suspending pure color pigment in a synthetic resin. This allows the color to retain its luminosity and depth, unlike traditional methods where pigments are often dulled by binding agents. The result is a striking, ultramarine-like color that appears to radiate from within. Klein used IKB extensively in his monochrome paintings and sculptures, aiming to evoke a sense of boundlessness and spiritual depth. This color quickly became synonymous with his artistic vision and remains a significant part of art history.

The color #0223B2, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments or color vision deficiencies. Its low luminance value results in poor contrast against light backgrounds, making text and other visual elements difficult to discern. According to WCAG guidelines, sufficient contrast ratios are crucial for readability and usability. To ensure accessibility, it's recommended to pair this color with very light hues like white or very pale yellow to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using #0223B2 to convey critical information without redundant cues, such as text labels or icons, to accommodate users who may not be able to distinguish it properly. Providing alternative color schemes or allowing users to customize colors can further enhance accessibility.
