title: Can I detect older monitors and supply them with web-safe colours?
body: <p>I want to use non-web-safe colors in several places on my website, including for the background. But I am concerned about visitors with older computers.</p>
  
  <p>Is there any code I can use that will change the color from the non-web-safe color to the nearest web-safe color if the visitor cannot see non-web-safe colors?</p>
