初学WPF，做一款小游戏练习一下

以前做项目的时候有用过Silverlight，最近了解了一下WPF，做了一款简单的小游戏来练手，希望能和大家多多交流。

想法：最强大脑 牛人多多，对色彩的分辨更是让人目瞪口呆，于是我就想到做一个小游戏，简单一点，做网格状的色块，中间穿插一块不同颜色但是又非常相近的颜色块，点击该颜色块即为通关，进入下一关，下一关的色块数量+1，直到到达一个差不多的关卡后不再+1；

效果如图

说做就做，新建工程，开始实现，首先准备好一组颜色相近的颜色代码，百度HTML颜色代码，随便选取，越相邻颜色色差越小。

 1  private string[][] colors = new string[][] {
 2             new string[2]{"#7B7B7B","#8E8E8E"} ,
 3             new string[2]{"#FF5151","#ff7575"} ,
 4             new string[2]{"#ffaad5","#FFC1E0"} ,
 5             new string[2]{"#DCB5FF","#E6CAFF"} ,
 6             new string[2]{"#79FF79","#93FF93"} ,
 7             new string[2]{"#97CBFF","#ACD6FF"} ,
 8             new string[2]{"#FFFF93","#FFFFAA"} ,
 9             new string[2]{"#B766AD","#C07AB8"} ,
10             new string[2]{"#B7FF4A","#C2FF68"}
11         };
