General Information about Astronaut Blue

The color #003B60, known as Astronaut Blue, is a deep, muted shade of blue often associated with professionalism, trustworthiness, and stability. In the RGB color model, it consists of 0% red, 23.14% green, and 37.65% blue. This composition results in a cool, calming tone that is commonly used in corporate branding and website design. The hex code #003B60 translates to a dark blue that evokes feelings of serenity and reliability, making it suitable for industries such as finance, technology, and healthcare. Its subtle nature allows it to be paired with a variety of other colors, from neutral tones like white and gray to brighter accents like yellow or orange, offering versatility in design applications. Due to the low lightness value, this color should only be used in combination with bright colors to ensure readability.

The hex color #003B60, also known as Astronaut Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to ensure sufficient contrast for readability, ideally achieving a contrast ratio that meets WCAG guidelines (at least 4.5:1 for normal text and 3:1 for large text). Without adequate contrast, users with visual impairments may struggle to read the content. It's crucial to test the color combination with accessibility tools to verify compliance. Moreover, consider providing alternative color schemes to cater to users with specific visual needs or preferences. This deep blue can be effective for creating a calm and professional atmosphere, but careful attention must be paid to its impact on readability and overall accessibility to ensure an inclusive user experience. Using it with colors like white (#FFFFFF) or a very light yellow (#FFFFE0) is advisable.
