International Klein Blue

#083AAC

General Information about International Klein Blue

International Klein Blue, represented by the hex code #083AAC, is a deep ultramarine blue hue. It is particularly notable due to its historical association with the French artist Yves Klein, who registered it as a trademark. This color is known for its intense saturation and matte finish, which contributes to its unique visual impact. Spectrally, it reflects very little green or red light, resulting in a pure and absorbing blue experience. In digital applications, #083AAC can evoke feelings of depth, creativity, and sophistication. Its unique properties make it suitable for artistic and design projects where a bold and memorable color is desired. The color is created through synthetic ultramarine combined with a matte resin binder, which suspends the color pigment and allows the pigment to maintain as much of its original qualities and color intensity as possible.

The hex color #083AAC, also known as International Klein Blue, presents some accessibility challenges, particularly in text applications. Due to its relatively low luminance, using it as a background color for white or light-colored text can provide sufficient contrast. However, using it for text on a white background can result in insufficient contrast, failing WCAG standards for readability. To ensure accessibility, it's best practice to use a color contrast checker to verify that the contrast ratio between the text and background colors meets the minimum requirements (4.5:1 for normal text and 3:1 for large text). Consider pairing it with lighter shades of yellow, beige, or even a very light tint of blue to maintain readability for all users, including those with visual impairments. Using this color for decorative elements rather than essential information also mitigates accessibility concerns. Ensure that any interactive elements using this color have sufficient visual cues for focus and hover states.
