CSS color() - Using pre-defined colorspaces

Following is an example showing the usage of predefined colorspaces with color() function with varying values of lightness, a-axis and b-axis:

<html>
<head>
<style>
   div {
      width: 100px;
      height: 100px;
      border: 2px solid black;
      margin-bottom: 10px;
   }
   
   .color-srgb {
      background-color: color(srgb 1 0 0);
   }  

   .color-srgb-linear {
      background-color: color(srgb-linear 0 1 0);
   }  

   .color-display-p3 {
      background-color: color(display-p3 0.4 0.6 35%);
   }  

   .color-a98-rgb {
      background-color: color(a98-rgb 1 1 0);
   }  

   .color-prophoto-rgb {
      background-color: color(prophoto-rgb 0 0 1);
      color: white ;
   }

   .color-rec2020 {
      background-color: color(rec2020 0.6 0.1 1 / 0.4);
   }
</style>
</head>
<body>
   <div class="color-srgb">color(srgb 1 0 0)</div>
   <div class="color-srgb-linear">color(srgb-linear 0 1 0)</div>
   <div class="color-display-p3">color(display-p3 0.4 0.6 35%)</div>
   <div class="color-a98-rgb">color(a98-rgb 1 1 0)</div>
   <div class="color-prophoto-rgb">color(prophoto-rgb 0 0 1)</div>
   <div class="color-rec2020">color(rec2020 0.6 0.1 1 / 0.4)</div>
</body>
</html>

CSS color() - Using xyz colorspaces

Following is an example showing the usage of xyz colorspaces with color() function with varying values of lightness, a-axis and b-axis:

<html>
<head>
<style>
   div {
      width: 100px;
      height: 100px;
      border: 2px solid black;
      margin-bottom: 10px;
   }
   
   .color-xyz {
      background-color: color(xyz 1 0 0);
   }  

   .color-xyz-d50 {
      background-color: color(xyz-d50 1 1 0);
   }  

   .color-xyz-d65 {
      background-color: color(xyz-d65 1 0 75% / 0.3);
   }  
</style>
</head>
<body>
   <div class="color-xyz">color(xyz 1 0 0)</div>
   <div class="color-xyz-d50">color(xyz-d50 1 1 0)</div>
   <div class="color-xyz-d65">color(xyz-d65 1 0 75% / 0.3)</div>
