可选颜色

"可选颜色"是Adobe Photoshop中的一条关于色彩调整的命令。但与色阶，色彩平衡和色相饱和度相比，就没有那么直观，所以大家常常遇到可选颜色时，并不是那么顺手，我也在网络上查了查关于可选颜色的教程，但基本上都是些以实例为主的，参数调好了，跟着一调，就OK了，但真正让自己调别的图的时候，又不知如何入手。或者效果不理想，干脆抛弃了这个很有用的调色工具！
我在这里就简单的给初学的朋友说说怎么调可选颜色
好的，我们现在开始进入可选颜色的忽悠话题：
如果真的想用好可选颜色，首先应该多了解一下色彩基础知识，否则还是一头雾水！

上面一张图是RGB三原色及其对应色的关系（有助于可选颜色的理解），接下来：
我们在PS中画出如下图形（绿色和蓝色图层混合模式改为滤色）：

这时候我们打开可选颜色调整对话框，首先调整红色：

看第一个调整色：青色！
青色代表什么呢？大家在RGB三原色及其对应色的关系中可以看出，青色是红色的对应色，如果我们把滑块向右拖动增加青色，红色是不是越来越黑了，那正是两个对应色混合，相互吸收的原理。
拖动滑块向左减少青色，大家看到什么？是不是没有变化呀，因为在红色本色就不具有青色

看第二个调整色：洋红！
红色是由洋红和黄色混合产生，我们这个红色已经是100%的纯红色，所以向右增加洋红，不会改变红色，向左减少洋红，会使红色部分越来越偏黄，降到-100，就变成纯黄色了。

看第三个调整色：黄色！
红色是由洋红和黄色混合产生，我们这个红色已经是100%的纯红色，所以向右增加黄色，不会改变红色，向左减少黄色，会使红色部分越来越偏洋红，降到-100，就变成洋红了。

看第四个调整色：黑色！
这个比较简单，是调整红色的明度，左明右暗。
好了，通过这一个色彩的调整，我们就应该知道其原理了吧，你可以试试别的颜色的调整，来提高对可选颜色的认识！
（以上认识属个人愚见，有错误之处，望老师们多指点）
