Demo: http://gavin-yyc.github.io/colorconvert/

  • rgb2hsl
  • rgb2hsv
  • rgb2hex
  • hsl2rgb
  • hsv2rgb
  • hex2rgb

Usage:

安装:

npm install --save @youc/colorconvert

Node Env

const cc = require('@youc/colorconvert');
cc.rgb2hsl(255, 34, 178);

ES6 Env

import cc from '@youc/colorconvert';
cc.rgb2hsl(255, 34, 178);

Browser Env

<script src="./colorConvert.js"></script>
<script>
var cc = window.colorConvert;
cc.rgb2hsl(255, 34, 178);
</script>

APIS:

rgb2hsl

参数分别为:redgreenblue对应的颜色值

cc.rgb2hsl(255, 34, 178); // [321, 100, 57]

rgb2hsv

参数分别为:redgreenblue对应的颜色值

cc.rgb2hsv(12, 1, 23); // [270, 96, 9]

rgb2hex

只有传透明度时才会返回透明度格式的rgb颜色值。

  • 透明度范围为0~100
  • 返回值字母皆为大写
// rgb
cc.rgb2hex(1, 2, 3); // #010203

// rgb with alpha
cc.rgb2hex(1, 2, 3, 67); // #010203AB

hsl2rgb

参数分别为:Hue, Saturation, Lightness

cc.hsl2rgb(321, 100, 57); // [255, 36, 178]

hsv2rgb

参数分别为:Hue, Saturation, Value

cc.hsv2rgb(321, 87, 100); // [255, 33, 177]

hex2rgb

可传入带透明度形式的hex值,返回值中alpha为0~100

cc.hex2rgb('#c23'); // [204, 34, 51]
cc.hex2rgb('#0C0117'); // [12, 1, 23]
cc.hex2rgb('#010203AB'); // [1, 2, 3, 67]

可省略#

cc.hex2rgb('0C0117'); // [12, 1, 23];

colorconvert's Issues

rgb2hsl方法,有一处写错了

第98行,计算s的第三个if,应该改成(max - min) / (2 - (max + min)),参考wiki

		//计算s
		if ( l == 0 || max == min ) {
			s = 0;
		}else if ( 0 < l && l <= 0.5 ) {
			s = ( max - min ) / ( max + min );
		}else if ( l > 0.5 ) {
			s = ( max - min ) / ( 2 - ( max - min ) ); // 这里有误
		};

转换问题

感谢制作这个工具!
不过我刚做了一些RGB2HSL, HSB的转换。为了验证准确性,转换回去看了一下。发现RGB2HSL中L的值一直是有一些问题,H和S正确,RGB2HSB正确。转换回去的功能上HSB2RGB整体有一些问题。因为没有读代码,主要是发出来也希望后续的使用者会注意到这个问题。
