  // Get cornflowerblue with an alpha value of 0.3...
  print(setAlpha(Color.cornflowerBlue, 0.3));
  // rgba(100,149,237,0.3)

  // Also works for hex and hsl expressions...
  print(setAlpha("#add8e6", 0.5));

  print(setAlpha("hsl(195, 53%, 79%)", 0.5));
  // rgba(173,216,230,0.5)

  // Which web color is nearest (30, 60, 120) in RGB-space?
  print(colorNearestRGB(30, 60, 120));
