General Information About Astronaut Blue

The hex color #01375D, often referred to as Astronaut Blue, is a deep, dark shade of blue that evokes feelings of tranquility and sophistication. Composed of very little red, a moderate amount of green, and a significant amount of blue, it closely resembles the color of the night sky or the depths of the ocean. In color theory, this color falls into the cool spectrum and can be associated with calmness, stability, and trustworthiness. Due to its dark nature, it is often used in design to create contrast or to convey a sense of professionalism and elegance. It's a color that commands attention without being overly assertive, making it a versatile choice for various applications across different fields.

The hex color #01375d, also known as Astronaut Blue, presents significant accessibility challenges due to its very dark nature. Its low luminance means it offers insufficient contrast against lighter backgrounds, which is crucial for users with visual impairments. According to WCAG guidelines, text or interactive elements using this color on a white background would likely fail contrast ratio tests, making it difficult for many users to read or interact with the content. To improve accessibility, consider using lighter shades of blue or pairing it with a much lighter foreground color such as white or a very light yellow. Tools that measure contrast ratios can help ensure your color choices meet accessibility standards, making your website or application more inclusive. Remember that proper color contrast benefits not only users with disabilities but also anyone viewing the content in varying lighting conditions or on different devices. Prioritizing accessibility will improve the usability and overall user experience.
