About International Klein Blue

International Klein Blue, or IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented the color to maintain its unique vibrancy and impact in his artistic creations. IKB achieves its remarkable intensity through a unique formulation that involves a synthetic ultramarine pigment suspended in a clear synthetic resin binder. This allows the pigment to retain its brilliance, unlike traditional paint mixtures. Its distinctive character makes it a prominent feature in modern and contemporary art. Its application extends beyond visual arts, it's now seen across various design fields, representing sophistication and innovation. The color has gained fame in art history, influencing design and culture, and remaining a symbol of artistic exploration and expression.

The hex color #0936ab, also known as International Klein Blue, presents significant accessibility challenges, primarily due to its dark hue and relatively low luminance. When used as a background color, it necessitates very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color might struggle to meet these ratios with many typical text colors. Therefore, designers and developers must meticulously check contrast ratios using accessibility tools. Careful consideration should also be given to users with visual impairments, who may find it difficult to distinguish text against such a dark background. Using this color sparingly and combining it with appropriate contrast is essential for inclusive design.
