International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. What makes IKB so striking is its intense purity and brilliance. Klein believed that this particular shade of blue best conveyed his artistic concepts, which often revolved around the immateriality and boundlessness of the universe. The pigment used to create IKB is a synthetic ultramarine pigment, known for its high tinting strength and exceptional lightfastness. Because of its unique qualities, IKB has become a recognized and iconic color in the art world and beyond, often associated with innovation, creativity, and depth.
The hex color #0029A0, also known as International Klein Blue, presents some accessibility challenges, especially in text applications. Due to its dark hue and low luminance, it requires careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for text and interactive elements. When using #0029A0 as a background, it's crucial to pair it with a light-colored text, such as white (#FFFFFF) or a very light gray, to meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Conversely, if #0029A0 is used for text, a much darker background is needed. Tools are available to calculate the contrast ratio between two colors, which helps designers verify that their color choices are accessible. Without adequate contrast, content can become unreadable, excluding users with low vision or color blindness.
