International Klein Blue
About International Klein Blue
International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color to maintain its uniqueness and association with his artistic vision. Chemically, IKB is a matte version of ultramarine blue, achieved by suspending the pigment in a synthetic resin. This unique formulation preserves the color's intensity and prevents it from appearing diluted, as often occurs with other mediums. IKB is renowned for its saturation and depth, often associated with a sense of infinity and the sublime. Its distinctive characteristic makes it a recognizable and impactful color in the art world and beyond.
The hex color #101CBA, also known as International Klein Blue, presents some accessibility challenges, especially for users with visual impairments. Its relatively low luminance value of approximately 5% means that text rendered in this color requires very light foreground text (white or very light shades) to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #101CBA as a background, it is crucial to ensure that all text and interactive elements meet these contrast requirements. Tools like contrast checkers can help assess whether the chosen color combinations provide adequate contrast. Additionally, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons can enhance accessibility for all users, including those with color vision deficiencies. Consider the impact on users with photosensitivity when using this intense hue.
