前言
相信大家平时工作的时候应该会经常用到颜色码吧，比如说想找个好看的颜色，或者有个颜色码但是不知道这个码是什么颜色的，这个时候我们就可以用颜色码对照表或者颜色码查询来查看了。
当然也可以用截图软件或者取色器或者PS来查看，不过这终究不是很方便、全面。这个时候我们可以自己写一个颜色码对照表，然后把它收藏到标签栏，用的时候随时打开随时用。
这个时候有人可能要说这种网站随便网上一搜多的是。是，确实有很多，但这终究是别人的网站，无法定制化。所谓定制化就是把自己经常用到的颜色用色块列出来，下次用的时候直接打开一看，你就知道具体颜色是什么样的，然后就可以复制颜色码使用了。不然每次用的时候又没记住码，去网站上找都找花了眼，然后还得去翻看以前的使用记录，看看到底是哪个颜色码。
所以自己写一个html，把自己经常用到的颜色写上去就很方便了。
效果
我们先来看看效果图吧。
最上面两个输入框，就是rgb和hex相互转换；输入颜色值后，输入框后面的小方块会自动变成对应的颜色，点击色块，自动复制颜色码。
中间那块就是颜色选择器，其中左边那一片色块区域，就是放自己经常用到的颜色码，直接点击色块，自动复制颜色码，并且右边的颜色选择器和两个输入框也会自动选择/输出对应的颜色。
最下面那块就是颜色大全，点击色块或者旁边的文字，都可以直接复制颜色码。
单击复制颜色码：
代码
接下来就是代码了。代码比较多，主要是最下面那块颜色大全是写死在html上的，不像上面那个常用颜色色块是动态创建的元素。因为考虑到这个颜色大全非常多，有五百多个td元素，这动态创建的话，我怕页面会卡，所以就直接写死了。这里的话我没有把那五百多个td元素写上了，完整的可以去资源下载或者是去我给的git链接上下载。
