About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0636AE, is a deep, intense shade of blue that is named after the French artist Yves Klein. Klein patented the color in 1957, recognizing its unique visual impact. Chemically, it is a matte ultramarine blue achieved through a specific formulation that enhances its saturation and intensity. This blue is often associated with concepts such as infinity, spirituality, and the sublime. It is known for its ability to evoke a sense of depth and boundlessness, making it a favorite among artists and designers looking to create visually arresting and emotionally resonant works. Its distinctive hue sets it apart from other blues, giving it a special place in the world of color and art.

The hex color #0636ae, also known as International Klein Blue, presents some accessibility challenges, especially when used for text. Its dark hue results in a low contrast ratio against white backgrounds, potentially making it difficult for users with visual impairments to read the text. To improve accessibility, it's crucial to use a light color for text on a #0636ae background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Tools like contrast checkers can help verify compliance. Also, avoid using #0636ae as the sole indicator for interactive elements; supplement it with other visual cues like underlines or icons to ensure usability for all users, including those with color blindness.
