International Klein Blue

#0422C6

General Information about #0422C6

The hex color #0422C6, often referred to as International Klein Blue (though this is a specific patented version), is a deep, vibrant shade of blue. In the RGB color model, it is composed of 1.57% red, 13.33% green, and 77.65% blue. Its primary association is with Yves Klein, a French artist who registered this particular intense ultramarine shade. The color is known for its purity and intensity. It conveys feelings of depth, stability, and confidence, making it a popular choice for representing authority and knowledge. It is worth noting that pure RGB values are seldom used in UI design, it is more common to use lighter shades for more usability.

The color #0422C6, a deep, saturated blue, presents significant accessibility challenges. Its low luminance value (very dark) means that text rendered in this color on a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Specifically, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Using this color for essential textual information without careful consideration of contrast is strongly discouraged. Consider pairing it with very light shades of yellow or white to achieve sufficient contrast. Also, avoid using this color as the sole indicator for interactive elements like links; provide additional visual cues like underlines or icons to ensure usability for users with color vision deficiencies. Thorough testing with accessibility evaluation tools is essential when implementing this color in user interfaces. It is advisable to use a color contrast checker to verify the contrast ratio between the foreground and background colors.
