About International Klein Blue

International Klein Blue, represented by the hex code #041FB0, is a deep, intense shade of blue that evokes feelings of depth, sophistication, and creativity. It is named after the French artist Yves Klein, who extensively used this color in his artworks. The color is achieved through a specific formulation of ultramarine pigment. In the RGB color model, #041FB0 consists of 1.6% red, 12.2% green, and 69% blue. It is a very pure and saturated blue that has a strong visual impact. The original goal when creating the color was to evoke the feeling of the ocean and the sky and symbolize boundlessness and infinity. This color can therefore be associated with inspiration, creativity and artistic freedom.

The hex color #041FB0, also known as International Klein Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure 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. Pairing #041FB0 with light colors like #FFFFFF (white) can help achieve an acceptable contrast ratio. However, it's crucial to test the color combination with accessibility tools to verify compliance. Avoid using #041FB0 for critical elements like links or form fields without proper contrast, as this can create barriers for users with visual impairments. Providing alternative color schemes can further enhance accessibility.
