About International Klein Blue

International Klein Blue (IKB), also known as #0613AE, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957 to maintain its unique visual impact, seeking to create a blue that embodied pure idea, the vastness of the sky, and the depths of the sea. IKB achieves its intensity through a specific binder that suspends the pigment while retaining its original qualities, leading to a vibrant, matte finish. This color became synonymous with Klein's work and is prominently featured in his monochrome paintings and sculptures. The color's distinctiveness lies in its ability to evoke a sense of infinity and transcendence. Its creation marked a significant moment in art history, highlighting the emotional and spiritual potential of color.

The hex color #0613AE, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance value of 0.01 makes it difficult to perceive against most backgrounds, especially white. According to WCAG guidelines, the contrast ratio with white is approximately 2.1:1, far below the minimum requirement of 4.5:1 for normal text and 3:1 for large text. This means text and interactive elements using #0613AE may be illegible for many users. To improve accessibility, consider using lighter text colors on this dark blue background or choosing a lighter shade of blue altogether. Proper color contrast is crucial for ensuring usability and inclusivity in web design. Tools like contrast checkers can help verify compliance with accessibility standards.
