Qt 自带颜色属性
Qt 系统自带颜色如下：
enum GlobalColor {color0,color1,black,white,darkGray,gray,lightGray,red,green,blue,cyan,magenta,yellow,darkRed,darkGreen,darkBlue,darkCyan,darkMagenta,darkYellow,transparent};对应颜色如下：
- color0: 这是自定义颜色，默认黑，RGB值为(255, 0, 0)
-

-

-
darkGray: (169, 169, 169)
-

-
lightGray: (211, 211, 211)
-
red: (255, 0, 0)

另外几个正常用到的颜色：
运行正常的绿色 (88, 206, 168)
