如何使HTML5颜色选择器返回颜色名称而不是颜色代码？

Question

<label for="background-color">Choose a color for background :</label> 
<input id="background-color" type="color" /> 

我希望这返回颜色名称而不是颜色代码，例如“蓝色”而不是“＃0000ff”。

 $(document).ready(function(){ $("#showPaletteOnly").spectrum({ showPaletteOnly: true, showPalette:true, hideAfterPaletteSelect:true, color: 'blanchedalmond', change: function(color) { printColor(color); }, palette:["red", "green", "blue"], }); }); function printColor(color) { alert(color.toName()); //var text = "You chose... " + color.toHexString(); //$(".label").text(text); } </script> 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script src="https://bgrins.github.io/spectrum/spectrum.js"></script> <link rel="stylesheet" type="text/css" href="https://bgrins.github.io/spectrum/spectrum.css"> <h2>Palette Only</h2> <input type='text' id="showPaletteOnly"/> <br /> <span class='label'>Choose a color</span> 

Answer 2

您可以使用java脚本库“Name that color” 。

<script type="text/javascript">

  var n_match  = ntc.name("#6195ED");
  n_rgb        = n_match[0]; // RGB value of closest match
  n_name       = n_match[1]; // Text string: Color name
  n_exactmatch = n_match[2]; // True if exact color match

  alert(n_match);

</script>
