About International Klein Blue

International Klein Blue, often referred to as IK Blue, is a deep shade of blue that was originally developed by the French artist Yves Klein. This color is renowned for its intense saturation and unique ultramarine pigment. Klein registered this color as a trademark to preserve its distinctive quality. IK Blue is created by suspending pure ultramarine pigment in a synthetic resin, which retains the color's brilliance. The hue evokes feelings of depth, transcendence, and boundless space. It has been widely adopted in art, design, and fashion to create visually striking and emotionally evocative effects. Its unique property allows it to appear almost as if it is radiating light, which has made it a favorite among artists and designers seeking to capture a sense of the infinite.

International Klein Blue (#053AAF) presents several accessibility considerations for web developers. Its relatively low luminance can create contrast issues when paired with light-colored text, making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Therefore, using white or very light gray text on an IK Blue background may not meet these standards. To improve accessibility, consider using darker text colors, increasing the text size, or adding a background overlay to lighten the IK Blue. Also, avoid using IK Blue as the sole indicator for interactive elements; provide additional cues like underlines or icons. Proper color contrast ensures readability and a better user experience for individuals with disabilities.
