General Information about #1E3F70

The hexadecimal color code #1E3F70 represents a dark shade of blue, often associated with feelings of calmness, stability, and trust. In the RGB (Red, Green, Blue) color model, #1E3F70 is composed of 11.76% red, 24.71% green, and 43.92% blue. This color is often referred to as 'Astronaut' due to its resemblance to the deep, dark blue of space. It is frequently employed in contexts where professionalism and reliability are desired, such as corporate branding and government websites. The color's relatively low brightness requires careful consideration of contrast when used with text to ensure readability and accessibility. In CMYK (Cyan, Magenta, Yellow, Key/Black) the color is composed of 73% cyan, 44% magenta, 0% yellow and 56% black.

The color #1E3F70, also known as Astronaut, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance (a measure of brightness) results in a low contrast ratio when paired with lighter text or background colors. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet Level AA compliance. When using #1E3F70, it's crucial to ensure sufficient contrast. Lighter shades of yellow, orange, or even pale greens often work well for text on a #1E3F70 background. Tools for checking color contrast ratios are readily available online and should be a standard part of the design process. Additionally, consider providing alternative visual cues, such as icons or labels, to supplement color-based information, ensuring usability for all users, including those with color vision deficiencies.
