About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. The color's visual impact comes from its heavy reliance on ultramarine, as well as Klein's matte, synthetic resin binder, which suspends the pigment and allows the color to achieve its maximum saturation and intensity. It's a vibrant, eye-catching blue that often evokes feelings of depth, stability, and confidence. It became the trademark color of the painter and was patented in 1957. The number of the color is also known as RAL 6004 in the RAL system.

The hex color #082EAC, also known as International Klein Blue, presents some accessibility challenges. Its dark hue results in a low contrast ratio against a standard white background, making it difficult for users with visual impairments to read text or distinguish elements. To improve accessibility, consider pairing this color with lighter shades like white, light gray, or a pale yellow. Ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is crucial for WCAG compliance. Avoid using this color for critical interactive elements or important information without adequate contrast. Utilizing tools that measure contrast ratios can help web developers to select more accessible color combinations. You can also provide alternative high contrast themes.
