About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0739AD, is a deep, saturated blue hue known for its striking visual impact. This color, patented by the artist Yves Klein, is a pure ultramarine pigment suspended in a synthetic resin, which retains the pigment's brilliance. This intense blue evokes feelings of depth, tranquility, and spirituality. It is a color often associated with the sky and the sea, representing vastness and serenity. In color psychology, blue is often linked to trust, loyalty, and intelligence, making International Klein Blue a popular choice for branding and design where these qualities are desired. Its intense nature and historical significance make it a compelling choice for artists and designers seeking to create impactful visual statements.

The hex color #0739AD, also known as International Klein Blue, presents several accessibility considerations. With a low luminance value, it may pose challenges for users with visual impairments if used as text on a white background. The contrast ratio would likely fall below the WCAG recommended levels, particularly for users with moderate visual impairments (AA conformance) or severe visual impairments (AAA conformance). To improve accessibility, consider using this color sparingly for decorative elements or pairing it with a very light color such as white or light yellow for text. Also, make sure interactive elements using this color have a minimum contrast ratio of 4.5:1 against the background color. Using a color contrast checker is highly advisable during the design phase.
