About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #091EAB, is a deep and vivid blue hue that was originally conceived and popularized by the French artist Yves Klein. Klein sought to capture the purest expression of blue, aiming for a color that would convey a sense of boundlessness and spiritual depth. He worked with a chemist to develop a unique matte finish that enhanced the color's intensity. The color's registration as a trademark reflects Klein's desire to protect his artistic vision. This specific shade of blue is frequently associated with concepts of art, creativity, and the infinite, making it a popular choice for designers seeking to evoke these themes. The hex code #091EAB signifies a precise combination of red, green, and blue light to reproduce this distinctive color on digital displays.

The hex color #091EAB, also known as International Klein Blue, presents significant accessibility challenges, especially for users with visual impairments. Its dark hue results in low contrast against lighter backgrounds, making text and interactive elements difficult to perceive. According to WCAG guidelines, sufficient contrast ratios are essential for readability and usability. To enhance accessibility, it's crucial to pair #091EAB with very light colors, such as 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 this color for crucial interface elements like buttons or links without providing clear visual cues, such as distinct borders or icons. Providing alternative text descriptions for images and using ARIA attributes can further improve accessibility for screen reader users. Thorough testing with accessibility evaluation tools and user feedback is necessary to ensure compliance with accessibility standards.
