The hex color #283373, also known as Astronaut, presents specific accessibility considerations, particularly in web design.

When using #283373 for backgrounds, designers should verify that foreground text meets these contrast thresholds, preventing visual strain and ensuring usability for individuals with visual impairments.

For example, using a slightly lighter shade or adding a subtle overlay to lighten the background can improve accessibility without drastically changing the color's aesthetic.
